Bb Contra Bass Clarinet
The contrabass clarinet is pitched in Bb, two octaves below the Bb soprano clarinet (one octave below the bass clarinet), with a range frequently extended downward to low D or C (the lowest Bb on the piano). Both the Eb and the Bb contra are most commonly found in bands and wind ensembles, and clarinet choirs.  Less often, one encounters them in orchestral music, pit orchestras, and the ocassional jazz solo. The Eb contrabass (also known as the "contra-alto" or "contralto") is also available in loop or straight forms, in metal or wood,
