Finding melodies on a single note instrument that really bring out the sound of more complex types of harmony is often a challenge. Here’s a Major 7 #5 melody I found the other day while doing some slow improvisation. It’s played in triplets starting on beat one for the bar.
Like many of the other material on the blog, I’d reccomend playing it displaced by one or two triplets as well and perhaps in 8th notes.
If you have the patience and/or carpal tunnel/RSI problems try singing the line with the mp3 below while visualising the fingerings. Using this method, you can practice a long time with no injury or fatigue plus it’s really much better ear training.
