On Chuck Mangione's Bellavia and Chase the clouds away,Is it a Alto flute playing the lead????I know Bob Mintzer uses one on McDougal street. Is the Alto flute a octave lower than the flute???Or is it a 4th or 5th lower and in a differant key other than C????For a adult just learning flute but w/30 years of sax playing can you start on alto flute????(I'm getting a closeout Deford regular flute from wwbw.com but if flute is bad{ie teacher doesn't like or plays out of tune} I was thinking of exchanging for a Emerson Alto flute)
