Lydian, the Disney mode…
Disney is not the only place you find Lydian, but it’s commonly used at the end of any song or other kind of music to let us know that we are someplace fantastic. In fact, I call it the “fantasy mode”. To get a feel for Lydian, try to write a tune that starts on F and ends on F that uses no sharps or flats. Then try adding chords that use no black keys. If you do it, you’ve written something using Lydian.
Here is a nice instructional video of Lydian on harp I like it because he does not talk much.:
I really like this next clip. It’s short, surprisingly effective, and it’s all about playing, not talk, talk, talk.
