Major 7sus4 Chord Trainer

Learn how a Major 7sus4 chord is built one semitone-count at a time — a sus4 chord (Lesson 28) with a major 7th stacked on top, instead of the minor 7th a dominant 7sus4 chord (Lesson 29) uses — then put it to work with three MIDI exercises: playing all 12 major 7sus4 chords around the circle of fourths, and 5 jazz plus 5 gospel chord progressions that show off its color, in every key.

How a Major 7sus4 chord is built

A Major 7sus4 chord — written maj7sus4 (e.g. Cmaj7sus4) — is a 4-note chord: a sus4 chord (Lesson 28) with a major 7th stacked on top, instead of the minor 7th a dominant 7sus4 chord (Lesson 29) uses. Every maj7sus4 chord — in any of the 12 keys — is built the exact same way, by counting semitones to the right from a root note:

  1. The starting note — this note names the chord.
  2. Count 5 semitones up from the root — the perfect 4th, replacing the 3rd exactly like a sus4 chord (Lesson 28).
  3. Count 2 more semitones up from the 4th (7 semitones from the root) — the perfect 5th.
  4. Count 4 more semitones up from the 5th (11 semitones from the root) — the major 7th, instead of the minor 7th a dominant 7sus4 chord (Lesson 29) uses.
Example — Cmaj7sus4: start on C, count 5 semitones right to reach F, count 2 semitones more to reach G, count 4 semitones more to reach B. C‑F‑G‑B is the Cmaj7sus4 chord.
A rarer, tense hybrid: the suspended 4th of a sus4 chord (Lesson 28) sitting right next to a major 7th only a half step away from the 5th above it — an unusual, tightly-packed color compared to the softer dominant 7sus4 chord (Lesson 29).

This MIDI exercise plays all 12 major 7sus4 chords, one after another, moving around the circle of fourths — each chord's root sits a perfect 4th (5 semitones) above the last one: C → F → B♭ → E♭ → A♭ → D♭ → G♭/F♯ → B → E → A → D → G → back to C. Every chord is played as a full 4-note Major 7sus4 chord (root, perfect 4th, perfect 5th, major 7th together).
