ChordCalc by Thinkyhead is a calculator for musical chords that combines superb chord notation abilities, simple chord editing tools, over a dozen interactive scales, drag-to-transpose, circular views, an interactive piano keyboard, and an intelligent fretboard all together into a simple, comprehensive musical tool.
ChordCalc is based on the music sequencer FretPet and shares the same interactive fretboard, scale palette, and circle views. ChordCalc isn’t a music sequencer, but it lets you use the same tools to make chords, explore scales, choose meaningful names, and hear how they sound on the guitar.
The version 1.0.4 update includes a new extended keyboard with musical symbols, smarter chord notation, and a fast, responsive fretboard with full notation of double-flat 7, flat 6, and sharp 11 tones.
