Most bass trombonists know and love the Bordogni vocalises, also known by some as the Rochut etudes. The purpose of this book is to provide some variety and possibly "fill in the gaps" in the Bordogni collection as well as provide a valid bass trombone alternative. Features:
• Some later etudes give octave ossia options.
• 20 additional pages present selected ‚tudes in higher and lower keys.
• Harmonic variety increases throughout the book even touching briefly on whole tone and diminished scales.
• Rhythmic complexity increases as the book progresses; odd meters and meter changes begin to appear sparingly.
• Each etude has a duet part.
