Hi. Am playing new alto and tenor, both Yamaha and am experiencing a new difficulty. Coming down in the higher octave F to E, the E sounds badly, E to Eb, the Eb is worse, Eb to D the D often does not sound at all. First had this with the alto and spent some time making sure it wasnt bad fingering, bad embouchure, just plain me, but then the tenor arrived and have the same thing but not so bad. Havent noticed this before on the same excercises with different alto. Never had a tenor before. Can sometimes overcome it with embouchure if I am ready for it, but not always. If I try the note change in isolation, not as part of the arpeggio, it sometimes happens, not always. If its just me I can overcome it but if anyone suspects an adjustment is needed I would be grateful to know.
