Open Score Editor also reveals a floating rhythm and repeat palette. Move it by its header, hide it with its close button, or reopen it with Rhythm & repeat palette. Drag note values, dotted rhythms, rests and repeat signs onto the five-line rhythm staff. Mouse and iPad touch dragging snap to the selected meter's beats and quarter-beat subdivisions. Rhythm marks stay with exported scores and are followed by chord playback and MIDI in Songbook.
Open Score Editor to start a four-bar chord chart. Drag the selected chord onto any beat; drop another chord there to replace it. Drag a placed chord or rhythm mark to move the pair to another beat or bar. Drop it outside the score, or select either part and press Delete or Backspace, to remove both. Escape cancels a drag. The + after the final bar duplicates that bar with all its contents. Press the + beside Chord score to reveal its controls; press - to hide them while keeping the score visible. Set the score meter and drag start/end repeat signs from the Score toolbox onto bars. Choose Plays and drag Repeat count onto a section to change its play count. Drag Numbered endings onto the bar after the last common bar; Bars per ending sets their length, and missing ending bars are added empty. On iPad, drag the chord name or Drag chord button with your finger onto a score beat. Keep your finger near an edge to scroll to another part of the chart. Meter changes rescale existing beat positions and durations to fit the new bars. Repeat order is preserved in saved score files and followed in MIDI and Songbook playback. Existing saved scores keep their original bar count. Delete Score clears this browser's draft after confirmation and starts a fresh four-bar score. It does not delete saved Songbook songs. Close Score hides the editor without deleting the draft. In guitar and notation views, the score occupies its own row below Selected notes, Chord Operations and Chord Library, beside the fretboard or notation staff, with View Controls remaining below. In piano view, the score sits below those same three boxes and above Chord inversion practice and View Controls.
In guitar view, View Controls sits beside Sound source and Volume, followed by the Download MIDI and Open Score Editor buttons and the Grid Size slider. Live MIDI keyboard controls sit below that group. Hover over View Controls or a fretboard note for wheel-scrolling and open-string keyboard guidance. Notation view uses a narrower staff with the tools alongside it, the same sound and export arrangement, and Live MIDI below. Grid Size is guitar-only.
Chord Dictionary is a reverse chord identification tool, it names chords by user selection on the fretboard, for guitar, piano, and note staff. Shows chord inversions on guitar and piano.
A fourth without a major or minor third is identified as sus4, including seventh chords with an omitted, natural, flat, or sharp fifth. When a third is present, the fourth can instead be named as an eleventh. In guitar view, chord identification and playback use the notes selected on the fretboard. The piano spans four octaves, C3 through B6. The staff uses treble and bass note dropdowns to add or remove pitches. Staff spellings follow the chord's intervals, including flats, sharps and double accidentals: A-7b5 uses A, C, E-flat and G. Playback starts at a low volume. Piano inversions wrap as a whole chord between the left and right ends of the keyboard.
Connect a USB MIDI keyboard or controller to your computer and press Connect MIDI. Select the input device, then play chords: Chord Dictionary shows a second, live keyboard underneath the full-width dictionary piano, with the menus below both keyboards. The lower keyboard identifies the harmony and marks the notes as you play and release them. Hold a chord and press the sustain pedal to copy it to the upper piano for analysis, playback and MIDI export. The copied chord remains there while you release the keys or try another chord. Each new pedal press captures the keys currently held, including notes spanning several octaves; the pedal also sustains sound normally. Use a Web MIDI-compatible browser such as Chrome or Edge; browsers without Web MIDI can still use all manual tools. Live input plays a velocity-sensitive piano sound through your computer, controlled by Volume, without sending MIDI back to your device. Disconnect MIDI to return to manual editing, or use Reset held notes if needed.
Cycle Show Note Names, Show Intervals and Show Blank Notes to choose labels on guitar and piano markers. Interval labels follow the selected chord root and library alterations.
Press Download MIDI to save the chord you are viewing as a Standard MIDI file. The chord is played as a single strum from the lowest to the highest note and rings for one bar of 4/4 at 120 BPM, with a guitar sound in guitar view and a piano sound in the piano and notation views. Drop the file into a DAW or notation program to build chord progressions, voice-leading studies or backing tracks from any guitar chord voicing. The Chord Library sits beside the chord name. In guitar view, the controls stay next to the fretboard, with 6-, 5- and 4-string layouts. In piano view, the keyboards stretch across the top and the menus sit underneath. In piano view, Chord Operations groups the inversion arrows, chord playback, note labels, Clear Chord, Download MIDI and Open Score Editor. View Controls sits beside Chord inversion practice; practice playback requires at least three distinct chord tones. Library Close Position, Drop 2 and Drop 3 selections start with the root in the bass; use the inversion arrows to explore other bass notes. Hold the pointer over a control for more than three seconds for contextual help in guitar and piano views. Keyboard focus also shows help; Escape dismisses it. Library voicing details are included in that hover help. Piano Volume and Sound source sit directly below the keyboard. Grid Size is shown only in guitar view.
Pick a root and one of 67 library chords: six basic triads, followed by major (with separate Major seventh, Dominant seventh and Other major groups), minor, augmented, diminished, sus4 and sus2 extensions. In piano or notation view, library chords load in the current view with their full set of tones, without guitar voicing reductions. Close position (root position) stacks chord tones in order, such as 1, 3, 5, 7. Choose Drop 2 or Drop 3 to lower the second- or third-highest note of the close-position chord by an octave; the voicing is centred in the lower-middle register of the piano, an octave below the previous library position. Root on string is guitar-only. Use the inversion buttons for piano inversions. Guitar also offers Close Position when the ordered pitches fit a playable shape. If a voicing or inversion is unavailable, the current chord remains displayed and a message explains why. All non-added-tone catalog templates are retained alongside the chart's altered 9th, 11th and 13th forms; equivalent templates appear once. Added-tone chords are excluded. The templates are transposed to the selected root. The neck moves to the right position and the chord voicing is placed on the fretboard with its intervals shown under each string. Choose the root on the 6th, 5th or 4th string, and switch between drop 3 voicings (the default) and drop 2 voicings. If drop 3 is not playable from the chosen root string, drop 2 is used. Extended templates follow the established voicing-reduction policy; any omitted intervals are listed rather than implying the full chord always fits one shape. The root, third or suspension, seventh and altered tones take priority: the natural fifth, ninth and eleventh are reduced first. Further tones may be omitted to obtain a playable shape within three fret positions whenever possible. Automatic shapes occupy at most four fret positions, or five only from fret 10 upward. The natural fifth can be omitted to retain upper extensions in a compact shape.
Open Score Editor to work on a lead sheet directly below the guitar or piano. Drag the selected chord button or chord name onto the score: a blue insertion cursor snaps to each beat, and releasing inserts the chord there. Move score below tools or above them to switch your workspace without losing edits. Create a new chord-only score here or reopen a saved score file (.json). Every bar has drop targets for each beat of the selected meter. Select a bar and use Duplicate measure to next to insert a copy without overwriting later measures. Select a score chord and use Open chord in Chord Dictionary to explore its voicing. Export the score to Songbook, download chord MIDI or an editable score file, or use Print / PDF and your browser's Save as PDF option. MIDI-file import and melody notation are currently unavailable.
Load a chord from the library without disconnecting your MIDI controller, then use the Chord inversion practice box below the chord tools and score. With at least three different chord tones selected, play close-position arpeggios through every inversion across one or two octaves. Choose Up and Down, Ascending or Descending, set the tempo, and use a four-beat count-in or turn it off. Up and Down repeats the highest inversion with its notes in reverse order before continuing down. Repeat the exercise or play it once. The upper keyboard follows the demonstration and extends its range automatically, while the lower keyboard keeps showing your playing. Stop practice restores the selected chord.
Pause keeps your place. Resume or the Space bar continues with the selected count-in; Stop resets the exercise. Space works outside text fields and other editing controls. Swing amount and Laid-back feel use the same 0–100% controls as Walking Bass and adjust live. Tempo, count-in and repeat changes pause; changing the direction or octave route stops. Loading a chord with the same inversion-pattern structure pauses at the current position; a different tone count or invalid chord stops the practice.
The Exercise position slider covers the complete inversion route. Drag forward or backward to hear short previews while the piano follows. Release during playback to continue at the selected note. You can also choose a starting point before Play or while paused; the next Play/Resume uses your selected count-in. Stop returns the slider to the start.
Your last chord is remembered when you come back, and the Share button links to exactly the chord you are viewing.
