Scales Pay attention to the name of the concert pitch. The name of the scale for your instrument may be different. Flute, Oboe, Bassoon, Trombone, Euphonium, and Tuba play the same scale as concert pitch. Trumpet and Clarinet go up one step (Concert B♭ is your C scale, Concert F is your G scale) Saxophones go down three steps. (Concert B♭ is your G scale) Horns go down 4 steps (Concert B♭ is your F Scale)
