Abbreviated sleeve notes in English:
"The Harz Canary: The inhabitants of the Harz Mountains in Germany have been breeding canary birds for several centuries, initially unknown in the rest of Europe. The name "Harz Canary" is derived from this mountain range, under which it is now commonly known. After discovering that these birds had a strong imitating talent, certain "tours" were taught to them, which now make up the entire song of the Harz Canary. Through careful selection and precise pairings, they have succeeded in "fixing" this learned song.
1. HOLLOW ROLL. The name originates from the rolling character and hollow sound of this tour. The hollow roll is an uninterrupted tour and, due to its wide tonal range and rich variation in structure, is one of the finest tours of the canary song. The hollow roll should be sung with the vowels: U - O, or OE (any other vowel is incorrect), and the consonant R, which should not dominate too strongly. The hollow roll sounds best when the R recedes and the vowels are connected by an H.
2. GRUNT. This tour is rightly called the bass of the canary song, and without the grunt, the song of the Harz Canary would be incomplete. The vowels are O or OE (any other vowel will devalue the grunt). The consonants are: K - N and R. The text of this tour is korrr, knorrr, koerrr, knoerrr. Different variations are possible, such as: round grunt (where the R is clearly "snoring"), hollow grunt (the consonants R and K practically recede), and matron grunt (a matron-like accent is clearly present). The grunt approaches perfection when it begins as a round grunt, transitions into a hollow grunt, and then ends as a matron grunt.
3. WATER ROLL. Water rolls are not heard as often in the canary song nowadays, as the bird tends to mix the "water" sound, which characterizes this tour, into other tours, causing them to lose depth. The proper base notes are formed by the vowels: U - O or OE. The consonants are: W - G - D - L - H - R, and B.
4. TREMBLE. Unlike the three tours discussed earlier, the tremble is an interrupted tour. The tremble can be recognized by the distinct, slightly trembling movement of the tones. The tempo of the tremble is slow, and the spacing between two notes is larger than that of the hollow bell. It can also be observed in the bird's movement, as it seems to tremble along. The proper base notes for a good tremble are: U - O or OE, and the consonants are: L or H. The value of the tremble is increased when the bird performs this tour from U to O or OE (falling tremble) and vice versa (rising tremble).
5. HOLLOW BELL. A good hollow bell is deep, sonorous, moderately fast-paced, and free from any extraneous sounds. The hollow bell is closely related to the tremble. The proper base notes are U - O or OE, with the consonants being: L or H. The hollow bell sounds beautiful when it transitions from U to O or OE (falling) and the consonant recedes.
6. MATRON. The matron is a compound tour that is difficult to breed and maintain in good quality. It can be easily recognized as the bird clearly "says" "matron" when singing. The proper base notes for a good matron are: U - O or OE, with the consonants being: GLK - BLK - and KLK. Different varieties exist, such as: hollow matron (purely on the OE vowel), water matron (sounds like "kloik"), bell matron (a soft I can be heard above the actual base note), etc. Additionally, there is the matron roll, where an R is woven between the different matron notes.
7. WHISTLING. One could say that every bird possesses whistling and expresses it. Due to their simple structure, they are easily recognizable to the listener. Although they are considered middle tours, a canary song would undoubtedly be incomplete without whistling. A good whistle can be produced on the vowels U - O or OE, and should be initiated with a D or soft T.
8. BELLS. Many breeders are somewhat hesitant to have a bell tour in a bird's song, as it can easily degenerate into sharp and shrill sounds. A good bell has the vowel I as its base, with the consonants being: L - H, or D. It sounds like a clear little bell and adds a desirable variation to the song. A bell roll has the vowel I as its base, with the consonant R."
