Could someone give me advice on tuning by ear? I'm new to orchestral trumpet playing and the requirement to tune to another instrument (and not a tuner). When the orchestra tunes, I can't tell if I'm out of tune or in tune. (So I'm pretty much relying on someone else to tell me...) It would be great if someone could suggest some things to listen for or some exercises to do to improve my ear. BTW, I can hear the 'beats' when other instruments are out of tune. However, when I tune, I can't hear them. Should I be able to? Thanks for all your help!
