Thank you very much for the sharing. For the initial recording, what string was recorded? Only the left one of each key?

Sounds pretty good! You did a good job. Thanks

0:00 How to tune an accordion 0:08 The accordion is taken apart with flat-nosed pliers. The nails must be pulled out straight, i.e. without leverage 1:02 The reed blocks of the treble side become visible. They are pressed against the filling with a metal plate 1:20 We remove a sound block from the accordion 1:28 filling of register slides 1:37 set of air valves 1:41 reed block from the front 1:44 from the top 1:47 from the back 1:51 underneath 1:54 Cross section 1:57 air chamber 1:59 reed block back 2:01 reed block body 2:03 reed block back 2:05 reed plate 2:07 reed 2:10 rivet 2:11 wax 2:13 filling 2:15 key rod 2:17 valve (pallet) 2:20 felt with leather 2:22 The valve opens. Air flows out of the accordion through the chamber (on push). The outer reed starts to vibrate 2:40 on pull: air is drawn into the accordion. The inner reed starts to vibrate 2:58 A reed blown by air from the wrong side will not vibrate. Nevertheless, some air flows through the gap between the reed and the reed plate 3:06 To prevent this loss of air, the reed plate has valve flaps made of leather or plastic. The thin valves are glued to the reed plate with special glue 4:25 The reed plate is nailed to the reed block. The nail head is cut off and the nail bent so that it presses the reed plate against the leather strip on the reed block base 4:35 leather strips 5:15 The advantage of nailing is that the reed plate can be easily removed from the reed block. Prerequisite for nailing is an absolutely flat surface on the reed block body 5:23 push 5:28 pull 5:33 Each reed plate has two reeds and two valves. The outer reed vibrates when pushing, the inner reed when pulling 5:42 Nailed reed plates are usually sealed against the reed block with varnish. It's even better if you press them into leather with screws 5:58 The reed plate is usually sealed with wax. The wax is also 'glue'. However, removing and reinstalling the reed plate is quite time-consuming 6:13 Wax dissolves well in white spirit. An acetone bath followed by a bath in white spirit and drying with compressed air is suitable for cleaning dirt and glue residue from the reed plates 6:25 Reed plates with rusty reeds should be replaced if possible. Moisture and rust are the accordion's greatest enemies. Cold often creates moisture! 6:33 This was just a brief introduction. The accordion that is actually being tuned is a two-part instrument with a free-bass. It has a total of 260 reeds, which are distributed over 4 reed blocks. Two reeds, one octave apart, always sound at the same time. No tremolo 6:44 This is how the untuned instrument sounds 6:57 The frequency of the tone that a reed produces depends not only on the reed itself, but also its surroundings (e.g. whether in the cassotto or not) and pressure when played. For this reason, the pitch of a reed outside of the instrument may be corrected, but never absolutely tuned 7:12 In order to know how much correction is to be made, the first step is to record as accurate a profile of the instrument as possible. The individual reeds are vibrated one after the other in the instrument with as constant a playing pressure as possible and recorded with Dirk's Accordion Tuner 7:25 First, a voice profile is recorded. Dirk's Accordion Tuner is set to 440 Hz and 1 reed. The "Auto" button should be clicked. The microphone is placed about 30cm in front of the sound outlet of the instrument. Ensure a quiet environment 7:38 The accordion is taken apart and the reed blocks partially covered with adhesive tape. If the accordion has register slides, this procedure can be dispensed with 8:15 The accordion is then reassembled. Each tone is played, measured and recorded individually. The author uses a prepared table chart. But you can also use the table chart provided with the accordion tuner 8:25 When playing, make sure that the playing pressure is constant until the chord tuner displays the message "locked". The measurement is reproducible to +-0.5 cents 8:47 Tuning chart: Note, values (Zug = pull, Dru = push), Remarks 9:01 After about 2 hours work, the finished table looks like this: The mean deviation is +2.3 cents. This corresponds to a fundamental frequency where A4 = 441.0 Hz 9:20 The table is now corrected: the average value of 2.3 cents is subtracted from each deviation. If the corrected deviation is more than 2 cents, the field is colored: blue for positive deviations, yellow for negative deviations 9:45 Now the reed blocks can be removed. Reeds that deviate from the target frequency by more than 2 cents are retuned on the tuning table 9:53 If the tone is too high (blue), the base of the reed is ground, if the tone is too low (yellow), the tip of the reed is filed 10:03 tools for grinding 10:08 Microphone, Tuning table 10:14 Tuning table bellows 10:20 laptop with Dirk's Accordion Tuner 10:25 magnet, reed retainer 10:36 In the first example, the note D# (8') is tuned on push. It is 3.7 cents too low 10:52 With the reed block removed, a deviation of -4.7 cents is measured. By filing the tip of the reed, the deviation should be brought to -4.7 + 3.7 = -1.0 cent. A few stages are usually necessary for this 11:16 target: -1.0 11:26 In the second example, the note D# (8') is tuned on pull. It is 7.6 cents too low 11:42 With the reed block removed, a deviation of -10 cents is measured. By filing the tip of the reed, the deviation should be brought to -10 + 7.6 = -2.4 cents 11:52 Since the reed is hidden under the valve, it must first be 'fished out'. The author uses a self-made tool with a magnet and pulls or pushes the reed upwards with it. Then it is clamped 12:34 target: -2.4 12:45 In the third example, the note F (8') is tuned on push. It is 2 cents too high 12:55 With the reed block removed, a deviation of -3.9 cents is measured. By filing the base of the reed, the deviation should be brought to -3.9 -2.0 = -5.9 cents 13:11 target -5.9 13:23 In the last example, the note G (8') is tuned on pull. It is 3.4 cents too high 13:32 With the reed block removed, a deviation of -4.6 cents is measured. By filing the base of the reed, the deviation should be brought to -4.6 - 3.4 = -8.0 cents. Because the reed is hidden, it first has to be 'fished out' and clamped 13:52 target: -8.0 13:58 And this is how the tuned instrument sounds 14:33 Although beats are completely frowned upon in concert accordions, the typical sound of the accordion is identified by its beats (also called tremolo). For example, a musette without beats is like a soup without salt 14:43 Beats occur when at least two tones with almost the same frequency sound simultaneously. A tone is heard whose amplitude periodically rises and falls. The greater the difference in frequency between the two tones, the higher the beat frequency 14:55 The beat frequency also depends on pitch. The higher the pitch, the greater the beat frequency. For example, two tones A4 (440 Hz), which are 20 cents out of tune with each other, have a beat frequency of 5 Hz 15:07 The higher the beat frequency, the 'sharper' the tone appears. If the beat frequency is greater than about 15 Hz, you clearly hear two tones and not a single tone with a beat. The following audio examples give an impression of this 15:19 Tone A4 440 Hz dry. No tremolo 15:24 Tone A4 440 Kz. Deviation 4 cents. Beat frequency 1 Hz 15:30 Tone A4 440 Kz. Deviation 8 cents. Beat frequency 2 Hz (French Canadian) 15:36 Tone A4 440 Kz. Deviation 16 cents. Beat frequency 4 Hz (Tex-Mex) 15:42 Tone A4 440 Kz. Deviation 20 cents. Beat frequency 5 Hz (Italian, French) 15:47 Tone A4 440 Kz. Deviation 40 cents. Beat frequency 10 Hz (extremely sharp) 15:53 Tone A3 220 Kz. Deviation 40 cents. Beat frequency 5 Hz (Sharpness is gone) 15:58 Tone A5 880 Kz. Deviation 40 cents. Beat frequency 20 Hz (clearly 2 tones) 16:04 Higher tones bear less deviation in cents than lower ones, although the beat frequency is usually chosen higher for higher tones than for lower ones. Every tuning professional uses his own tuning profile by which he can also be recognized 16:15 Before the tremolo is impressed on an accordion, the octaves must be tuned properly. Professionals then tune the reeds of the tremolo by ear. Dirk's Accordion Tuner also provides the non-professional with powerful tools for tuning the tremolo. However, the explanation of these tools is beyond the scope of this video 16:34 Thanks for watching! www.dirksprojects.nl

So beautiful accordin teacher thank you sir how to tuning accordin🙏💐

what does the free trial include?

Wonderful information.

Thanks Dirk, I am a little more confident in taking on this project myself. any recommendations on the tuning tool?

My significant other has perfect pitch, but we need actual tools. Is there a popular and more reliable brand?

How do I pick proper tools for a particular 'older' console piano?

Great job.

What I don't understand is: Why can't you just tune every string to a pre-determined frequency? Why does the software have to calculate anything at all?

I would take my accordion to you if I lived in your country.

Very cool. They say you learn something new every day. Well, this is my "something" today.

I have not watched a single second of this video nor do I have any concrete knowledge about piano tuning but 'quick and easy' has me on edge lol

how to bring it back to 0? you just keep pressing the key and push the string?

Excellent video thank you Dirk. 😊

whats the song at the end?

That was great Dirk, Thankyou!

Incredible! Thank you!

great video. love the swiss accent. thanks!

Brilliant. Thanks

I just bought my first piano and I have question. How do u know when to dampen the right 2 strings and the left?? Did I miss something? Lol thx for ur vid. I want to learn pisno soooooo bad.

Oh that's gonna take FOREEEEEEEVER!!! NOOO😭😭

This is very thorough, thank you.

Thank you for the Video, i have a some questions. 1. is Dirk Piano Tuner free to download? if not how much is it? 2. what are you hold in your hand? is it part of tuning piano or are you using it for your voice for the Video? 3. where can i get tuning kit and damper(not sure spelling) stick? how much are they? 4. The michrophone at foot panel, is it usb at the end? how does it connect to laptop? thanks

what piece is the one you played on the last?

Damn dude as a programmer looking at this it must have been a fucking journey to make this.

If it listens only one string per note, how do you tune the other strings from the same note?

Everyone is overlooking the fact that this cost $400 dollars? You can just call a professional for $150 or even less.

Great video

I don't understand the stretch part. I thought, that every single key, has a desired frequency, that should be the same in every piano. Why does this software calculate the desired frequency for the piano that is being tuned? Does that mean, that two different pianos played in a duo, may sound "out of tune"?

well it’s not quick or super easy but it works!

What is That red thing in 4:30 ?

Great Video i Just watched it on 150% speed and forgot it after a while and only realized it at the end when you were playing the Song at the end

The current tuning software supports both Mac OS and Windows. Check out our website www.dirksprojects.com for a trial copy of Dirk’s Piano Tuner and further details on the supported operating systems.

English subtitles are now available. Check out our website www.dirksprojects.com for more information on the accordion tuner, other available tuners and products.

Wow! Thank you for sharing. Blessings.

Dinksproject thank you for the explanation one question though will it tune in this method in concert pitch? even though my piano is extremely out of tune? Thanks

How long does the whole process take? About 2 hours?

1:13 My family when they're listening me playing

What mean "professional standard" in this case, please?

Your K for the half ton is 1.059515... WHY?

Does this work on keyboards?

Probably a dumb question, but this works on grand pianos as well yes?

1:02 That hurt to listen to...

Damn it would have been prime if he actually said "one hour later"

GOOD VIDEO

OMG, this is horrendously tedious! My piano tuner tunes my upright in like 15 minutes and it turns out perfect. I'm not sure what the purpose of all this nonsense is. It appears that this would take potentially hours!

Thanks for the great video Dirk! I have a question about the recording part. When you are recording the keys with multi-strings, do you record each string? Or do you only record a single string? If it's only one string, does it matter which? Is there any further instruction about that we should know. Thanks again for the fab video, Dirk!
