🎹 Chord Calculator & Finder
Build chords or identify what you're playing
The Chord Calculator & Finder is a dual-purpose music theory tool that allows users to either build chords by selecting a root note and chord type, or identify chords by clicking notes on an interactive piano keyboard. In build mode, users can explore various chord types from basic triads to complex extensions like 9th chords, while the find mode analyzes selected notes and suggests all possible chord matches with exact and partial match indicators. The tool provides comprehensive chord information including note breakdowns, fingering tips, and visual feedback, making it perfect for musicians learning chord theory, pianists exploring new voicings, or anyone trying to identify unfamiliar chord progressions.
