The corrector of intonation imperfections in 3 or 4 vlve brass instruments solves the intonation imperfections in all 3 or 4 valve brass instruments f.e.: trumpet, French horn, ventile trombone, tube, tenor horn, bass tuba, fanfare in the following way: by means of a compensation slide the adequate adjustments of the pipe length occur. The intonation imperfections in wind instruments are marked by the following: If using the 5th, 6th and 7th pipe length an insufficiency of the instrument's pipe length occurs. For that reason all three vertical sequences of tones, played at those lengths, are relatively too low. Of the 10 monstly used tones from the harmonics only the following are correct and have an intonation precision: 4 tones 1st, 2nd, 4th and 8th tone. Three tones are too high 3rd, 6th and 9th tone and three tones are too low 5th, 7th and 10th tone. If, by means of a compensation slide, the basic pipe length is shortened, the intonation of the played tone raises. If, by means of a compensation slide, the basic pipe length is lengthened, the intonation of the played tone is decreased. |
