There are so many things to work on in the practice studio! I'm like a kid in a candy store when I come to my flute. However, I realize there are some folks who don't share my enthusiasm! Deciding what to work on that day may be dependent on time available, or immediate needs such as an upcoming rehearsal or performance. In general, balanced practice for me means spending about 1/3 the time on basics (tone production, scales, arpeggios, double tonguing), 1/3 on repertory, and the remaining 1/3 on piccolo work. This way I'm able to touch on everything important. Write out a list if it helps you organize your time. Warm up quickly and musically....those first sounds of the day should set the 'tone' for your practice session.
