Bass Lessons - Musical bass tab
This, sorry, is not a tab. It can show you to play well-musically.
If you were ever to be in a gig at the last moment, you would need to know what
key a part of the piece was in. From then on, the only thing you can do is play
the notes in that note's scale.
Try, for about 5 minutes each day, to create your own tunes with the notes
of a scale.
Another point: a good thing to do then make a piece(such as a 12-bar blues)
by playing the notes in one scale, ALWAYS staring on the note that the scale
starts on, in one bar, and then changing the key.
