I've got my 20minute A2 Performance in a few weeks time
, my theme is "tuba solos composed or arranged in the 20th century" which covers pretty much every tuba piece there is! 
So far, my program consists of:
RONDO
From Concerto for Double Bass
Antonio Capuzzi (arr. Phillip Catelinet)
HORNPIPE
American Folk Dance
arr. Herbert Wekselblatt
HAPPY
Tuba Study
Derek Bourgeois
ALLEGRO
From Sonata No. 3
Antonio Vivaldi (arr. Ken Swanson)
RESTFUL PRELUDE
Six Little Tuba Pieces
Gordon Jacob
2.10mins
I GOT RYTHEM
A little light music for tuba
Gershwin (arr. John Iveson)
I've got space for one more piece, to make it 20mins. I'm looking for a grade 7 piece - but I can't preview any before ordering - so I wondered if anyone had any ideas about what might fit into my program well!
I know I can't be too fussy, but a slow moving, perhaps lower-middle register one would fit in very well.
If anyone has any advice, I'd be really greatful.
Thankyou
