Explore Chords, Scales and Harmony

Find a chord name from the notes you choose on a guitar fretboard, piano keyboard or interactive grand staff. Chord Dictionary identifies harmony and inversions, offers alternative chord names, and shows the notes and intervals that make up your selection. Guitar layouts support six, five or four strings.

Choose from 67 library chords and explore playable Drop 2 and Drop 3 guitar shapes, or full piano voicings including Close position. Listen to a chord, move through its inversions, or download it as MIDI for a music application. In piano mode, practise arpeggiated inversions over one or two octaves with tempo, count-in, direction and repeat controls.

Connect a MIDI controller in a compatible browser to see your playing on a separate keyboard. Hold a chord and press the sustain pedal to copy its exact voicing to the dictionary piano. You can load library chords without disconnecting your controller, making it easy to play along with a chord or the inversion practice example.

Turn the notes of a melody, riff or chord into a list of possible scales. Select three or more notes and What Scale is it searches for scales that contain them. Compare the suggested roots and scale names to investigate a key centre or discover another harmonic setting for the same notes.

Add or remove notes to refine the matches, listen to your selection, and compare the results before committing to a key. It is a useful starting point for improvisation, composition and ear training: a matching scale is a possibility to explore, not a claim that every melody has only one correct key.

Create chord scores in Chord Dictionary, then import and save them in Songbook. Edit chord changes and organise the harmony into measures. Songbook analyses a progression to suggest its key centres and harmonic functions, helping you follow how a tune moves rather than treating every chord as an isolated shape.

Compare traditional harmonic analysis with a simpler triad-based view, and use the colour-coded chart to spot relationships and changes of key. Play the chart to hear the movement of the chords while you study it, making the songbook a place to prepare tunes, explore progressions and practise harmony.

Explore 130 scales on a horizontal guitar neck or piano keyboard. Choose a root and scale, then see its notes or intervals laid out across the instrument. The guitar view covers a 22-fret neck so you can connect scale shapes and recognise the same tones in different positions.

Hear the scale ascending, descending or going up and back. Practise one to four octaves, adjust the tempo and explore degree-skip patterns instead of always moving step by step. The visual notes and guided playback help connect scale theory with the sounds and fingerings you practise.

Practise major, minor, augmented, diminished, sus4 and sus2 triads through their inversions. Follow guitar string groups or a piano keyboard, choose the direction and tempo, and loop an exercise. Piano practice also supports two hands one or two octaves apart, with the keyboard extending when the exercise needs more space.

Build progressions from Roman-numeral chords, popular changes and saved presets. Combine separate key centres, transpose a group or individual chord, and cycle exercises through keys by interval. Follow the letter-named chords on the circle of fifths to keep track of where the harmony is going. Download an exercise as MIDI to practise elsewhere.

With a MIDI controller connected in a compatible browser, play along on a second keyboard. When you stop, review correct, wrong, off and missed notes alongside early/late timing and progress over repeated passes. Download the results and graph as a PDF, or clear the report and start a fresh exercise.

Learn jazz walking bass with eight original lessons: steady roots, root-and-fifth two feel, chord-tone walking, scale connections, chromatic approaches, major and minor ii–V–I, and a twelve-bar blues.

Follow the four-string bass fretboard or piano keyboard. Set tempo, meter, count-in and loop; practise a single key, all twelve keys, interval cycles or your own key group. Download the bass line as MIDI and hear the next chord root before you play it.
