Those performing solos at Solo & Ensemble Contest: see the IHSA Instrumental Scales PDF for the major scales for all instruments in the correct ranges. You will also be asked to play a chromatic scale, which are the documents below.
You will be asked to play the scales in concert pitch. If you're a transposing instrument, be sure you are transposing correctly.
Bb Instrments (Clarinet, Trumpet, Tenor Sax, Baritone TC): go up a whole step from the scale they ask (concert C = your D)
F Instruments (Horn): go up a fifth from the scale they ask (concert C = your G)
Eb Instruments (Alto & Bari Sax): go down three half steps from the scale they say (concert C = your A)
C Instruments (Flute, Oboe, Trombone, Tuba, Baritone BC): you play what is asked (concert C = your C)
