How It Works
This chord generator uses Web Audio API to synthesize multiple frequencies simultaneously, creating harmonic relationships that form musical chords. Select your root note, choose from 16 different chord types, adjust the octave, and hit play to hear the result.
Choose any note from C to B as your root, then select a chord quality from basic triads to extended jazz chords like 9ths.
Move the chord up or down with octave controls, choose a waveform that fits your sound, and dial in the perfect volume and sustain time.
Hit play to hear all notes together, or enable the arpeggiator to hear each note separately in sequence.
Professional Chord Generator - Key Features
This chord generator is designed for musicians, producers, and students learning music theory. You get 16 different chord types covering everything from basic major and minor triads to sophisticated jazz voicings like major 9ths and half-diminished 7ths.
The arpeggiator feature breaks chords into individual notes played in sequence, which helps you hear the internal structure more clearly. Adjust the arpeggiator speed to match your workflow.
Four waveform options let you shape the timbre. Sine waves give you pure tones perfect for ear training. Triangle waves add some harmonic content without being harsh. Square waves produce that hollow organ sound. Sawtooth waves are bright and rich, similar to analog synthesizers.
Use this tool to learn chord construction, test progressions for your songs, practice identifying chords by ear, or just explore the world of harmony.
