Hi Johnny,
Just filled in a pitch tendency chart for my alto Sax.
After a good warm up, tuned up the sax, and then went through every key from Low Bb to High F# with a tuner, and recorded how sharp or flat each one was.
I did this mainly cause my middle D always sounds a bit off when i flow through the chromatic scales!
The pitch tendency chart showed the middle D to be twice as sharp as the rest of the keys on the sax.
My question to you, is now i know that my middle D is too sharp whats the best way to bring the pitch down when playing it?
Is it use less air or less lip pressure?
or are there any other tricks without losing tone?
