French trombonist and composer Gerard Pichaureau (b. 1916) collaborated with trombonist Marcel Galiègue to compile an excellent series to aid the learning of Trombone studies. The first album of Préambule addresses a variety of aspects including scales rhythm arpeggios intervals time signatures accidentals and performance directions among other features. Moreover the detailed instructions are in French English German Spanish and Japanese making for a highly versatile book. For all aspiring Trombone players Pichaureau andGaliègue's Préambule fills a large gap by aiding the progress and understanding of technique from the beginning.
