Question:
A violinist freind hears phantom notes unrelated to the played chords when she plays the violin and..?
another plays the flute. These phantom notes are like low humming and have vibrato. Is there something going on with harmonics or beat notes or something? Has anyone else heard them?
Answers:
These can also be called difference tones. I am a professional flutist and teacher. When I play duets with a student, and I am playing a note that vibrates at 1000 cycles per second, and she is playing one at 800 cycles, per second, then the humming note is the *difference* - 200 cycles per second. These can be used for learning. I have student play scales with me, in thirds. We invert each interval. If the DIFFERENCE note stays exactly in tune, then we are, also. If the note migrates, then at least one of us is slightly unstable in pitch.
