Here’s a line based on a major seventh sound.

As the line descends, the first two notes of each grouping of four expands – the first two are a minor third (G#-B), the next two are a major third (E-G#), and the last two are a perfect fourth (C#-F#).

The line also works over a major ii-V-I, starting from the 13 of the ii chord, the root of the V chord, and ending on the major seventh.
