POWER-CHROMATIC is a very expressive repeat-scale tuning I invented for my own use in 1980, and have used ever since. It has only two notes different to Solo tuning, but they have a big effect: now every single draw note can be bent! This makes for great bluesy expression as well as enabling you to play jazzy tunes with ease, using draw bending alone. Many different keys and positions are possible, allowing you to try several and choose the best one for a particular piece.
The PowerChromatic Lucky 13 is half-valved, giving strong blow notes with the ability to add vibrato and isolated-reed pitch bending, plus all those juicy draw bends in every hole.
PowerChromatic comes in the keys of C, D and G. If you already play PowerBender Tuning, PowerChromatic will be easy to learn - because it is the same scale as holes 4-7 of PowerBender, repeated!
