A cassette is available with the review etudes of the Melodic Foundation Studies played by Mark Alison Morton. Melodic Duets includes fourteen double bass duets with levels ranging from post-elementary to intermediate advanced. This book is an adjunct to the whole series of Studies for Double Bass and are filled with fun and phrasing. The Technical Foundation Studies , in two volumes, give special emphasis to two very important aspects of double bass playing for the advancing bassist. Similarly, Volume 2 emphasizes development of the thumb positions above the first octave and below.
Ample practice is given for moving between the closed and open hand and thumb fingering systems.
The studies and etudes also provide ample practice in the treble and tenor clefs. Nine etudes of Volume 2 are available on cassette as performed by Mark Alison Morton. Orchestral Tunings A short, but helpful book, that promotes Three Alternative Orchestral Tunings for the Double Bass is available. These tunings provide an alternative to using a clumsy extension mechanism or adding a fifth string to the double bass. Combined with the quick response of modern strings and the more common use of the 4 finger technique in the higher positions, these alternative tunings allow players to reach the low ranges necessary for good orchestral playing.
