THE OCTAVE
It's time to look at a musical pattern that is very common in bass playing, the "octave." An octave is the same note up or down eight letters in the musical alphabet. For instance, the last two notes in the previous example were both E, but one was high, and one was low—that is an octave.
The octave follows a physical pattern on the fingerboard. From any note on the E (or A) string, move up 2 frets, and across 2 strings. This pattern is consistent throughout the fingerboard.
Fingering an octave (without an open string) requires you to play the low note with the first finger, and the high note with the fourth finger.
For fingerstyle, use your index finger (i) for the low note of an octave and your middle finger (m) for the higher note.
This example uses the octave shape. For fingerstyle, make sure to drop the right thumb onto the E string when making the jump across to play the D string. This example also shifts up with the first finger to 2nd position. Shifting around the octave shape is a very common practice in bass playing.
