Shostakovich: Festive Overture 

David Werden
use alternate fingering if they help you get it up to speed. I'd suggest practicing it both ways. You may find that one way works well for a while, but the other may be better as your technique develops.

Snap down the fingers like a machine. Everything must be rhythmically even. Be sure you are playing the articulation as marked, especially bars 3-6 of Rehearsal # 9. In bars 6 and 7 of Rehearsal #22, you may use 1st valve for the concert G-flats, but in an audition situation (i.e.. playing solo for a panel) the degraded intonation and tone quality may be audible to the more discerning listeners. I prefer using the regular fingering (2&3) unless the tempo exceeds Quarter= 1 80 (a tempo some conductors exceed in concert situations). I suggest learning to play it both ways in case the auditioner gives you a tempo faster than your personal limit using the standard fingering.
