Gb Major Scale — Notes, Chords & Free MIDI
The Gb Major scale is Gb, Ab, Bb, Cb, Db, Eb, F. Free MIDI download, with the chord built on every degree of the key — no sign-up.
The reference scale everything else is measured against: seven notes, a leading tone a semitone under the tonic, and a home chord that resolves completely. In Gb Major the notes are Gb, Ab, Bb, Cb, Db, Eb, F, written with 6 flats (Bb, Eb, Ab, Db, Gb, Cb). Its relative minor is Eb Minor. The interval that gives it its sound is the natural 7 pulling to the tonic. This page presets the scale tool to Gb Major (also called the Ionian mode) — play it, or download it as MIDI with or without the chords.

How it works
Choose a root note and a scale, and this tool builds a MIDI file containing the scale played ascending and descending in quarter notes. Enable diatonic chords to also include the triad built on every degree of the scale — a quick way to hear which chords belong to a key. Press play preview to hear the exact notes before downloading. This page arrives preset to Gb Major, so the preview and the download both start on Gb4 and climb through the scale from there.

- Feed it to arpeggiators or samplers that expect incoming MIDI.
A Gb Major reference lane earns its keep fast: with Gb, Ab, Bb, Cb, Db, Eb, F laid out on the piano roll, one glance tells you whether a note in your melody belongs to the scale or is a deliberate colour tone.
