Over the past few months I've come across interesting ideas thru two books that I have been studying. The first is a book by some guy named Piston, and it's about Harmony, the second is Nicholas Slominsky's Scales and Melodic Patterns. The ideas are this: increasing and diminishing intervals and also mirror intervals. Anyone out there familar with these concepts? I've found that by applying them to my melodic playing, using these concepts have helped me break out of "patterns" and "licks" and to play fresh ideas and concepts. Increasing and diminishing intervals go something like this: increasing would be if you play C to D, that is 1 to 2, now play D to F which is 1-m3, then F to A, which is 1 - 3, and so forth and so on............. diminishing would be the same idea in reverse. Mirror intervals would be if you played 1 -3 and then what note is the 1 the 3rd of. Anyone else run across this idea? How have you used it in your playing? Any suggestions?
