How to play
- Click or drag across frets to pluck individual notes.
-
Pick an Instrument at the top — Guitar, Bass, Ukulele, Banjo, or
Mandolin. Each one swaps the tuning, fret count, and sound list. Your last-used sound
is remembered per instrument.
-
Strum Bar (Guitar / Ukulele / Banjo / Mandolin): the row of named
chord pads at the top of the chord builder is the fastest way to play a song. Every
chord you play (via the matrix below or the + input) gets pinned here, so
a progression like
Em → A → Em → A is one tap per change once both
chords are on the bar. Pads persist across sessions per-instrument, capped at 8
(oldest falls off). Hover or tap-and-hold a pad to reveal the × remove
button.
-
Chord builder (Guitar / Ukulele / Banjo / Mandolin): set Quality
(Major / m7 / sus4 / aug / dim / mMaj7 / 6 / m6 / m7â™5 / …) and Shape — those just
configure the chord without playing. Tapping a Root button strums it
(and pins it to the Strum Bar above for one-tap recall later). The five enharmonic
roots show both spellings (C♯ / Dâ™, D♯ / Eâ™,
F♯ / Gâ™, G♯ / Aâ™, A♯ / Bâ™) — the
+ name input also accepts either form (Bb7 and
A#7 land on the same chord). Guitar and ukulele voicings (with textbook
fingerings) for the seven core qualities come from the open
chords-db
dataset; the extended qualities (aug / dim / dim7 / m7â™5 / mMaj7 / 6 / m6) and banjo
/ mandolin chords use an algorithmic finder that searches three position windows
(open / mid / high) for each chord.
-
Reading a chord shape: see the legend row at the bottom of the chord
builder. Finger numbers follow the universal string-instrument convention —
1 = index, 2 = middle, 3 = ring, 4 = pinky — used in every guitar,
ukulele, banjo, and mandolin method book. The
red disc shows the chord's
root note name (e.g. C for a C major chord) with the fretting
finger number as a small superscript (e.g. C₃ = press the C with your ring finger).
-
Strings (low to high):
E A D G B E. The thicker strings
are toward the bottom. On narrow screens the neck scrolls horizontally — swipe past
the inlay dots to reach the upper register.
