D# Lydian, Piano Side

7 notes to the octave, lit below across two octaves of this reader's keyboard, with every key numbered by where it sits in the scale. The numbers are the useful part mid-bar: a chart moves under you, and the thing you need is which degree is still under the hand — not where the run started.

Major with a raised 4th (#4) — dreamy, ethereal, and floating. Often called the brightest mode, with an otherworldly suspended quality.

Heard in: Film scores, progressive rock, jazz — Joe Satriani's "Flying in a Blue Dream", John Williams, Steve Vai.

The right hand takes the fill and the left keeps the written number sounding under it, so a piano reader hears every note of the scale against the chord the chart called rather than in place of it.

Run it hands together until the window stops being a pattern, then take it to a chart counted in D# and let the numbers pick their own notes out of it.
