Certain scales are especially suited for constructing chromatic phrases, and the half-whole step diminished scale is particularly handy for guitar improvisation.
Example 1 is based on the fact that each shape from the half/whole step diminished scale can be repeated a minor third apart. So these phrases are all Major 3rd arpeggios ( CMaj, EbMaj, GbMaj and A Maj) repeated a minor third above the previous.
Example 2 is mixing up the approach to the scale by using intervals instead of scale phrases.
Example 3 Naturally other concepts can be combined with the half/whole step diminished scale to create chromatic phrases, this example includes a passing note (g# the #5).
Example 4 C half/whole step diminished, moving a phrase chromatically down the scale.
