Another method of alternating the bass uses
notes which are selected according to musical
theory regarding chord construction.
Chords are constructed from notes of scales.
The most important chord is the major chord
and is constructed from the major scale.
Notes 1 3 and 5 are used from the major scale
to construct a major chord. For a C major
chord we would use the C major scale e.g.
TONIC

The strongest bass note is note 1 with note 5
being the next strongest so it sounds good to
alternate using notes 1 and 5. Often these
notes are called tonic for note 1 and dominant
for note 5. Therefore this system is often
called the tonic-dominant alternating bass or of
course the 1-5 alternating bass.
Here is a chart of where notes 1 and 5 are for
each chord. You will notice that some strings
we weren't allowed to use before are now used.
