Good afternoon! I already wrote 50 or 60 marches for piano and this is my 3rd or 4th one for some type of ensemble and the 1st one actually for wind band. Feedback much appreciated. The score is in Russian and I'm too lazy to translate it, but here's the instrumentation:

1. Piccolo;
2. 2 flutes;
3. 3 clarinets in B-flat;
4. Bass clarinet in B-flat;
5. 2 alto saxophones;
6. Tenor saxophone;
7. Baritone saxophone;
8. 3 trumpets in B-flat;
9. Flugelhorn;

13. Euphonium;
14. Tuba;
15. Timpani[1];
16. Glockenspiel;
17. Hand cymbals;
