| Mike,
While a younger improviser can "survive" on the two scales and their modes I think your comment isn't really 100% accurate. Outside of the Whole Tone and Diminished scales you have many scales based on non-European theory that neither come from the major or ascending melodic minor (jazz minor) scale. Yusef Lateef's "Repository of Scales and Melodic Patterns" has tons of examples outside of your parameters.
One of my favorites is the Archaic Greek scales... but I'm crazy!
One of the joys in more advanced improvisation is finding other alternatives to the basic scale choices mentioned above. |
