A second name for the same keys
Look at the four top notes of Emaj9: G# B D# F#. They form G#m7. So Emaj9 is E in the bass with G#m7 on top, an easy way to find it fast.
Where Emaj9 is used
- Emaj9 is the I chord of E major and the IV chord of B major.
- It replaces Emaj7 when a song wants a softer, wider sound.
Make Emaj9 automatic
- Say the notes out loud while you press them: E, G#, B, D# and F#.
- Switch between Emaj7 and Emaj9 ten times without looking at your hand.
- Alternate root position and a rootless shape with the 3rd on the bottom, keeping shared notes still.
- Last, meet Emaj9 mixed with chords you already know, in an order you did not plan.
Five minutes a day is enough to make Emaj9 feel easy.
