Once you know the fingering for each scale form, practice each one using various sequence patterns, as in the following examples. The first one uses the A form of C major.
This one uses a triplet sequence played in the G form.
Now try a triplet run using hammer-ons and pull-offs played in the D form of the C major scale. If you are not familiar with these techniques, see Progressive Guitar Method: Lead .
It is important to remember that scales are just the raw material for making music and are not an end in themselves. The purpose of learning all the forms and practicing sequence patterns is to become comfortable with them in order to make melodic statements.
Once you are confident with the scale forms, experiment using various techniques, (e.g., bends, hammer-ons, slides, etc) and create some of your own licks and solos from them. The next example is a lick derived from the G form of the C major scale. The ballad at the end of this lesson moves between all the forms of the major scale, so be sure you know all the fingerings.
