A set of 76 duets for any combination of two bass clef instruments (tuba players will have to read trombone-octave scoring). Set in a wide variety of tempi and meters. Most are in flat keys or the key of C/Am. All are in the bass clef. All duets are either one or two pages, and none requires a page turn. No composer names are indicated. Though the title says "Advanced Duets," these actually range from intermediate to advanced, making them especially well suited for better high school players on up through college and beyond. 144 pages.
