G Major Scale — Notes, Chords & Free MIDI

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 G Major the notes are G, A, B, C, D, E, F#, written with 1 sharp (F#). Its relative minor is E Minor. The interval that gives it its sound is the natural 7 pulling to the tonic. This page presets the scale tool to G 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 G Major, so the preview and the download both start on G4 and climb through the scale from there.

What can you do with a scale MIDI file?

• Drag it into your DAW as a reference lane while writing melodies.
• Learn unfamiliar scales — modes, pentatonics, harmonic minor — by seeing them on a piano roll.
• Feed it to arpeggiators or samplers that expect incoming MIDI.

A G Major reference lane earns its keep fast: with G, A, B, C, D, E, 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.
