Identify chords from live MIDI or manual note entry, follow the key as you play, then explore the harmony behind them. Stop guessing what chord you're playing. WhatChord gives musicians fast, musically informed chord names and live key context. Connect a Bluetooth or USB MIDI keyboard for instant feedback, or use the lookup pad to enter notes from any instrument, sheet music, or recording. Auto key detection listens to your recent live chords, shows confidence, and waits when the evidence is ambiguous. Explore Chords and Explore Scales let you build and hear chords, browse a wide range of scales, inspect keyboard patterns, and understand diatonic harmony. Play it. Explore it. Learn it. WhatChord goes beyond simple note matching. Its musically informed analysis considers inversions, extensions, slash chords, altered tones, key context, and conventional naming practices so chord names appear the way musicians expect to see them. When you're comping with a bassist, Ensemble mode names rootless voicings as the chords they imply and marks the implied root on the keyboard.
