Three Trio Sonatas (Neuheit Posaune) A new set of three beautiful sounding Corelli, Trio Sonatas for Trombone Trio have been transcribed by retired L.A. Philharmonic Principal Trombonist, Ralph Sauer. Opus 1, No. 2 in D major Opus 1, No. 3 in G major Opus 4, No. 1 in C major Each trio of about eight minutes in length is in a four movement structure of Slow-Fast-Slow-Fast. There are many great pure chorale harmonies and each second movement has a contrapuntal style to it, which is great for building up keen ears and ensemble sense. The Sonatas are of moderately advanced difficulty, in Tenor and Bass Clefs. Endurance is not a problem because of the masterful editing of Mr. Sauer. The pieces can be performed by most College/University students and some advanced high schoolers. Range goes from a pedal A for Bass Trombone to one high D for the 1st part, but most of the tessitura is in a normal range.
