To start with, you need to go to a local violin shop and ask them to build a bass violin for you. Don’t worry about how your violin sounds; you don’t need to be a professional to know how to tune one. There are different different ways that you can tune a bass violin.
There are three ways that basses are tuned: to Cm, Eb and F#:
Cm or diatonic tuning (a.k.a. “straight-up C”)
(a.k.a. “straight-up C”) Dantophone (a.k.a. “quarter tone C”)
(a.k.a. “quarter tone C”) Eb or triad (a.k.a. “quartertone Eb”)
Tune your basses using the E-bow and the A-Bow. You can use the A-Bow (for flat notes), but it’s better to use the E-Bow to get more accuracy and control and more strength. (For example, to play an E-bow note, press and hold the E-bow string as you slide your finger up and down the E-bow).
When you play with the E-Bow, it makes it more difficult to play sharp notes, as the E-Bow is more powerful than the A-Bow, and the E-Bow is slower than the A-Bow (unless you have trained your finger to be faster with the E-Bow). To find out about the best way to tune a bass from A to E, check out this article on Piano Tuning by Chris Taylor, professor of music at Indiana University.
Once you have an A-Bow in your fingerboard, you can play a C-bow, an F-bow or an A-Bow. If you play the E-Bow, you’ll get more strength in your fingertips. Since the E-Bow is slightly slower than the A-Bow, you may need to use the F-bow for some of your music. This is a very practical trick for playing finger-tuned or finger-free violin or viola from E to C, B to A and D to E.
The third way to tune a bass is Dantopop, “quarter tone D”. You can play this as a D-bow with just your ring finger; it’s a nice, mellow sound.
