Read directly from the server with tools/list, grouped by what they act on.
If a tool disappears, we record the date.
capo
find_capo
Works out where to put a capo. Give the key you want to sound in (for example to match a singer or a recording) and, optionally, the open-chord key you want to play shapes in. Returns the capo fret, or the easy options if no shape key is given.
chord
get_chord_shapes
Returns playable guitar shapes for a chord name (open position and movable barre shapes), with frets, fingering where known, the notes in the chord and a text chord diagram. Handles major, minor, 7, maj7, m7, sus2, sus4, add9, 6, m6, 9, dim, m7b5, dim7, aug, power chords and slash chords such as G/B.
guitar
guitar_level_check
A quick self-assessment that places a guitarist on Fretwork's 10-stage learning path (Stage 0 Getting Started to Stage 9 Artistry) from yes/no answers to up to nine questions about what they can already play, and says what to learn next. The questions build on each other, so answers are read in order up to the first "no". Called with no answers, it returns the nine questions.
identify
identify_chord
Names the chord a guitarist is holding from the fret on each string (standard tuning), lists its notes and returns a chord diagram. Use when someone asks "what chord is this?" and gives frets like x32010, 3-2-0-0-0-3 or "0 2 2 1 0 0" (low E string first; x = muted string).
key
find_key
Works out the most likely key of a song from its chord progression, gives each chord its Roman numeral, lists the other chords that belong to the key, and suggests which scale to solo with.
make
make_practice_plan
Builds a daily guitar practice routine and a 4-week focus plan sized to the player's level, the minutes they have each day and their goal (songs, strumming, fingerpicking, lead, barre chords, theory or general). Uses Fretwork's 10-stage curriculum, where stage 0 is for someone who has never played.
scale
get_scale
Gives the notes of a scale in any key and where they fall on the guitar fretboard (standard tuning), string by string, with root notes marked. Scales: major, natural minor, harmonic minor, melodic minor, the seven modes (dorian, phrygian, lydian, mixolydian, locrian), minor pentatonic, major pentatonic, blues and major blues.
songs
find_songs
Finds songs a guitarist can play with the chords they already know, from Fretwork's free library of 87 public-domain folk, gospel, blues, campfire and Christmas songs. Each song has chords, key, time signature, level and a free play-along page. Can also list songs that need just one or two new chords.
transpose
transpose_chords
Moves a song's chords to a new key. Accepts a chord list, a chord chart with lyrics (chord lines are transposed, lyric lines are kept), or inline [C] chords. Give either from_key and to_key, or a number of semitones. Also suggests capo positions that let the guitarist keep easy open shapes in the new key.
