How to play
-
Click or drag
across frets to pluck individual notes.
-
Pick an
Instrument
at the top β 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 β A β Em β 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
Γ
remove button.
-
Chord builder
(Guitar / Ukulele / Banjo / Mandolin): set Quality (Major / m7 / sus4 / aug / dim / mMaj7
/ 6 / m6 / m7β5 / β¦) and Shape β 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 (
Cβ― / Dβ
,
Dβ― / Eβ
,
Fβ― / Gβ
,
Gβ― / Aβ
,
Aβ― / Bβ
) β 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 / m7β5 / 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 β
1 = index, 2 = middle, 3 = ring, 4 = pinky
β 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. Cβ =
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 β swipe past the inlay dots to reach the upper register.
