10 Melodious Etudes - Vol.1 The 120 Melodious Etudes of Marco Bordogni were introduced in a three-volume set in 1928 by Trombonist Joannes Rochut and have been used for almost 100 years as pedagogical tools primarily in the low brass world. Their bel canto style, using beautiful tone and precise legato are their hallmark. Bass Trombonist Nir Fishkin has artfully arranged 10 Melodious Etudes for Brass Quintet which are suitable for moderately advanced performers. The arrangements spread the melody around between the five parts. The Trumpet parts are in B-flat.
