What Are the Different Types of 4-String Banjos? : Banjo Basics

[@gxtmfa]

Great presenter. I have a nasty suspicion I’d walk away with a banjo if I ever met him. He’s probably an amazing salesman.

[@gshomeweighttraining6284]

right, i only went in to ask him where the petrol station was.and i came out with 3 banjos.

[@ricban1950]

About a year ago I put Irish Tenor Banjo strings on my Banjo Ukulele and tuned it BGDE like my Baritone Ukulele. This lets me play it the same way as the Baritone Uke. It has a much better sound now particularly when fingerpicking. The scale length is 16.5 inches and the tensions involved are very close to the tensions with nylon strings so there was no risk of it breaking.

[@jamesmcbroom3755]

Another use of the tenor banjo is in traditional Irish music, where you mostly pick the tune's notes rather than play chords.

[@Nicholas-dreamlove]

I recently purchased an Irish Tenor Banjo with 4 strings. I need to learn how to play it.

[@janaldencornish]

Wonderful video. Funny how he switched the banjo uke for a banjo mandolin right there at the end without explicit mention.

[@stepno]

Maybe he didn't want to explain mandolins and double strings before lunch... And the even more confusing "melody banjo," essentially a mandolin banjo with single (steel) strings instead of pairs. Possibly designed to confuse Banjolele players.

My father bought me a SS Stewart short banjo for $40 in 1960. It was the folk craze, but I found it drowned everyone out, so I switched to a stand-up Bass. Your explanation answers a lot of questions I had. Still have the banjo.

[@jimmcintyre4390]

Love his enthusiasm. I could hangout in his store all day.

[@stepno]

Love the magic trick at 5:52 where the banjo ukulele is replaced by a banjo mandolin, with no explanation. Mandolin banjo has four unison pairs ("courses") of strings tuned in fifths like a mandolin or fiddle, and with the fingerboard about the same size as a mandolin or fiddle. Very loud. Tuning gg-dd-aa-ee. There is yet another variation called a Melody banjo, which is basically a mandolin banjo with single strings instead of pairs. It can also be very loud, but sweeter, without the jangle and overtones you can get from the doubled strings.

[@JerryJr65]

Thank You for explaining this!!! I play both 5 & 4 string, & i start to feel like a complete nerd, trying to make people understand the difference.

[@johnsteinmetz6721]

Really informative, as a guitar player (12-6-3 string) I always wanted to expand to banjo, thanks for the info

[@garycstube]

My mother played a tenor banjo. I never knew the history. This was great! Thanks.

[@100purejuice]

Those riffs are amazing! I enjoyed this quite a bit

[@RockStarOscarStern634]

1:05 The first thing that Banjo makers started to realize is that if you take off the 5th String, then you have Banjo that instead of playing with your fingers you can use a Pick which they call it a Plectrum Banjo. The lack of a Drone String on the Plectrum Banjo (Tenor Banjo, Banjitar, etc) made it alot easier to play in Jazz players keys.

[@danielaruta8816]

Great presentation on banjo types. Thanks for this video.

[@memriloc]

ABSOLUTELY LOVE THIS VID. Have an antique banjo uke that I'm busting to refurbish. Have a five sting that I have no idea how to play then just today picked up (although I like vintage this isn't) a six string sx that I think I'm gonna try Nashville tuning on after I clean it up.

[@mrbodhranhead]

I have yet another variation. I own a 1929 Paramount Melody banjo. Scale slightly shorter than a mandolin. Resonator, bell brass tone ring, and the same body as a Lange model 'B'. I'm not sure of the original tuning, so I have mine tuned as a mandolin. I've never seen another quite like it. It was on the wall next to its big brother, a Paramount plectrum banjo, and it just followed me home. I'll post video sometime soon.

[@nanocyde_artist]

Very cool. I have a Washburn Melody 4-string from the early 20s. Possibly the loudest unamplified string instrument I've ever heard!

Another variation is Irish Tenor Banjo. It's the same as a plain Tenor Banjo, but with different strings, and tuned lower, not like a viola, but like a mandolin, or violin. Can be heard over the loud flutes and fiddles.

I accidentally bought irish tenor strings when I should have gotten regular ones. 😂 Oh well, guess a little more bass can't hurt.

[@RockStarOscarStern634]

@@JBergmansson It never hurts to have those low notes especially if you wanna star picking the Bachs Violin Sonatas and Partitas on the Tenor Banjo since that lower tuning is good for Violin pieces.

@@RockStarOscarStern634 Yeah, I've also tried the prelude from cello sonata number 1 (transposed from G to D), sound pretty cool! You miss out on the really high register a bit though. That piercing, sparkling chordwork that dixieland banjo players can do.

@@JBergmansson Yeah, the Banjitar also was used in Dixieland Jazz because back in the 1920s and 30s before we had amps, we used Banjitars to compete with the Horns. The Tenor Banjo tuned CGDA (along with the Tenor Guitar in the same tuning) is what you'll hear in Dixieland Jazz.

[@RockStarOscarStern634]

0:58 This is why I'm getting a Banjitar soon. It was really inconvenient to have that 5th String Ringing away out of key, especially cause horn players like to play in Flat keys. So the 1st thing that occurred to Banjo makers was you could take the 5the String off the Banjo & only have the 4 playing Strings. If you take the 5th String off the Banjo, & only have the 4 Playing Strings, then you have a Banjo that instead of playing with your fingers, you can play with a Pick which they called it a Plectrum Banjo about 100 years ago, & this makes it easier to play in flat keys. There are also 5 String Plectrum Banjos played famously by Scargold that add on a Low F String which broadened the range. Banjitars had that same idea.

[@MrDanoconnor]

Excellent Video, very informative and well done. I tried playing some Christmas songs this year, flanked by a Trumpet and Clarinet and when we played the video back, My Banjo was Totally Drowned out by the two wind instruments, Couldn't hear a Note coming from my Banjo!

Scargold played the 5 String Plectrum Banjo which has a Low F String added to it, & it broadened his range.

[@darz3829]

FYI_ the earliest 5 string banjos were played as a legitimate instrument. They were played with bare fingers, with gut strings, a skin head, and played mostly classical and ragtime pieces, done in the same way that Segovia would have played them. The fifth string as a drone came much later. And the idea that tenor banjo "cuts" better is based solely on the fact that the top string is tuned high. In truth, there are 3 strings tuned exactly the same for plectrum and tenor (CGD). He uses the term long neck tenor. Most folks know tenors as 17 fret and 19 fret. Both are considered short neck banjos (compared to 22 fret plectrums). Notice also that his strumming style is only on the neck, not much on the head - that will not give you the varieties of tone possible with a banjo. The main thing that he neglected to mention is what the strengths of the different types of banjos. Tenor banjos (17 & 19 fret) excel at single string lines. They can play chords but the voicing is very wide, equivalent to playing a chord on piano with all your fingers stretched out. Plectrum banjos can play chords voiced closer, thus allowing ease of playing prettier chords with less effort. Playing single string lines on plectrum is not as precise as tenor, but playing band key melodies with chords is easy on plectrums. A good compromise for guitar players is a tuning called "Chicago." It's the top 4 strings of a guitar, usually done on a 22 fret banjo. It too has close voicing but melodies are a bit more difficult to get.

[@Unwritten_Pages]

I just got a 20 fret resonator 4 string banjo, I haven't got new strings yet but I've got it tune dGBE so re entrant Chicago tuning mostly resembling the ukulele.

[@bredlo]

This was great! Been looking at a 4-string on Craigslist, and think I may pull the trigger after watching this.

[@raceface_m2579]

I honestly thought there were only 3 types. Wow. Thank you!

[@sarafwolf]

Awesome video! So can you tune a standard tenor to viola tuning or mandolin tuning? Your choice? I'd rather play in GDAE since I know the chords but my grandpa's old banjo I have is tuned CGDA. I'd play jazz and Irish trad stuff both.

[@MT-kc6rq]

The late, ever-lamented Barney McKenna single-handedly made the GDAE tuning the standard one. For keltic picking, anyway. If you listen to one of his soloes it won't be hard to understand why.

[@takinisurvivalchannel3812]

I have the same question, and can't find an answer. I play the 5 string, and mandolin, but inherited a Challenger 4 string tuned in CGDA, and tried to tune it to GDAE, way off. I believe your have to buy the Irish tenor strings.

[@MountainHomeJerrel]

I actually just uploaded a video on my channel that shows using classical guitar strings in my Banjo Ukulele to tune it with standard DGBD, and now it has become one of my favorites banjos to play in terms of tone.

Something I immediately noticed when I got my resonator tenor banjo was... that it doesn't have an "indoor voice." It wants to be heard... by neighbors... in other counties. And dammit, it will not be ignored!! It's a banjo that screams, "HEY! LOOK AT ME!!" :) I am curious as to what strings you have/had on the ukulele banjo. The only uke strings I ever see are nylon. Are you using steel strings from another instrument or what? If so, which instrument and which size strings? Only asking because I'm tempted to try and make one from a cigar box or something.

I had a Epiphone 5 string banjo. The extra peg being on the kneck was my main issue. I play 6 string guitars, 4 string Bass. so did my dad, he thought my first banjo should be closer to those in amount of strings, so it would be easier to start. He was so wrong it made things so much harder. I sold it to Guitar Center, and baught a Bass. I sold my bass not long before i got the banjo, regreted it. I only got a banjo because i wanted to play folk songs like some folk, Sea Shanties i was really into, still into. the chords i managed to learn was easy, i picked them up rather fast. Sadly my fingerpicking was too crude and not precise enough, i am uncapable of understanding how to play wt the lessons was throwing at me. Now i know that there actually are 4 string Banjo's. I'd love to get one. Although, If i could get a Lute. I'd possibly choose the Lute😂 Thankfully wt i got from that Banjo had improved my Guitar, Bass skills. I currently own 8 Guitars, 1 Bass. Fender Malibu CE, Stargazer UPP.6, Starcaster Strat single coil by Fender, Jackson JS 10 Dinky, a Jackson Flying V, Epiphone Les Paul Special, Fender Stratocaster Blacktop HH, a Vintage Harmony Acoustic Guitar, Yamaha RBX260 Bass. 4 Amplifiers. Marshall MG 15 CD Series Guitar Amp, Peavey Rage 158 Transtube series Guitar Amp, Crate MXB10 Combo Bass Amp, Roland MicroCube 225 COSM Guitar Amp. Of course i have some more gear but i'm just going to end it here for now.

[@mountaingirl1797]

Is it hard to learn to learn to play the ukulele banjo❓thank you ‼️

[@mazda1942]

The chords are the same but you have to "attack" the ukulele banjo. I first taught myself to play the uke in my teen years (1950s) when skiffle was all the rage. Much later in the 1980s I discovered George Formby and his ukulele banjo playing. I first found a 1940s GH&S Melody uke, but it had severe limitations and sounded quite dull. My fortune changed in 2003 when I bought a 1927 Gibson UB4 and the sound was astonishing. I never looked back. I still play my wooden uke at home but for any gigs I use the Gibson. The main adjustment when playing either one is that you need to really strike the UB4 with gusto. I grow my first finger and thumb nails long so the nails strike the strings hard and give a lovely "ring" as a banjo should.

[@PWS777]

[@jakeglanville6835]

Excellent presentation and very informative. What about the piccolo banjo? Are these always 5-string? I ask because my banjo-ukulele which has never had more than 4-strings on it, has been called a piccolo banjo by some. It pre-dates all the banjo-ukes I know of, as it must have been made before the end of 1904 when William Temlett its maker, died, so some have claimed it cannot be a banjo-ukulele. What's the difference between a banjo-uke and a piccolo banjo, apart from the number of strings? Black Jake of Norwich, England.

I have a really beginner question. Can I get a beginner 5 string banjo, remove the 5th sting and tune it to Irish tenor banjo tuning? I would really like to get a tenor banjo but all of them seems to be out of my price range and the only banjos I can afford are either ukulele types or the 5 sting variations.

[@AaronQuickDesign]

You could probably get away with a varied tuning, still in 5ths, but tuning the low D to a G is a big jump. Standard 5 string tuning is (G)DGBD, Irish tenor tends to be GDAE, might be able to get away with something akin to a DGAD. It'll sound a bit more like an Bouzouki tuning (just with the low strings swapped). If you're not worried about volume, you can get a tenor guitar for 200-300.

[@darz3829]

Quite a few players take a 5 string banjo and remove the 5th string. But they tune it to either plectrum or Chicago tuning. The reason is - generally speaking - the 5 string is tuned roughly the same as plectrum. But if you try to tune a plectrum length banjo to tenor tuning it won't work for a number of reasons. At this time 2021 there are many affordable tenors. Try the BanjoHangout.org classifieds. A good price would be around $500-$750. Anything less wouldn't be worth it.

[@crazyace02]

A great bit of information, but how did the Irish Tenor Banjo come about?

[@SirSelby]

It's the same as a regular tenor banjo, it just made it's way over to Ireland after initially being used for Jazz in the U.S. I will add that in Irish music it's usually tuned to GDAE instead of CGDA, to suit the music better.

[@crazyace02]

The Irish tenor banjo may have started out the same as the standard tenor, but it is not same today. Thanks to Barney McKenna it is now made with fewer frets,19 or 17. And is tuned to GDAE. Tunes are played using singe notes, as with the fiddle, onamented with triptets. Whereas jaz tenor banjos are played with fast stumming of chords to bring out the melody.

[@SirSelby]

^ I assume he was asking about the instrument itself, rather than the playing. Many Irish players are still playing the old tenor banjos, exactly the instruments that were used in Jazz. People just decided to add the word "Irish" on the front of the instrument, the same as with "irish flute", or "irish whistle", neither of which are Irish instruments. Also, 17 fret tenor banjos were around first, prior to the 1920's. Barney McKenna is likely responsible for the GDAE tuning, but the tenor banjos used today are in most cases not a different instrument at all than early tenor banjos (especially considering that early tenor banjos are still widely played!)

[@SeymourSunshine]

Today, the standard tenor banjo has a 19-fret neck and the Irish tenor has a shorter 17-fret neck. Having said that, plenty of banjo players just choose the neck length they like, the tuning they like, the music they like and just have loads of fun belting it out. As the presenter said, you can't play sad music on a banjo. Can you imagine singing about misery, death and destruction with a banjo plinking away in the background? No!!! Banjos are for fun people playing fun music.

[@SirSelby]

"Irish Tenor Banjo" is a tenor banjo, but people, for some reason, like to put "Irish" in front of the name of any instrument used to play Irish traditional music. I've heard people say they play "the irish fiddle", when they are playing a regular fiddle/violin. It isn't a different instrument. I promise you, 17 fret and 19 fret tenor banjos were around for a good while before the instrument was even used in Irish trad. You can easily google vintage 17 fret tenor banjos to verify this. The 17 frets isn't a new idea, and you can find vintage instruments with those same details. Tuning an instrument differently doesn't make it a different instrument, either. If the only thing majorly different about the instrument is how it's tuned, then it hardly warrants classifying it as a different instrument. If I tune a guitar in Drop D tuning is it not a guitar anymore? The instrument is a tenor banjo. You can call it an Irish Tenor Banjo if you like, but it's still a tenor banjo.

[@maitland1007]

Thanks.. where do Irish banjos fit into this?

[@Ladeenian]

An Irish banjo is exactly the same instrument as a tenor banjo EXCEPT that slightly thicker strings are used. That way it can be tuned lower, to GDAE for Irish songs, instead of the usual CGDA tenor tuning.
