The E ♭ clarinet is used in orchestras , concert bands , marching bands , and plays a particularly central role in clarinet choirs , carrying the high melodies that would be treacherous for the B ♭ clarinet. Solo repertoire is limited.The E flat clarinet is the smallest of the standard clarinets, about a third shorter than the
B flat- or A-clarinets. It is noted in E flat, which gives it its name. The notes are noted in the violine key and
fingering is the same as on a B flat clarinet - except that everything is a bit narrower.
