• 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).

• 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…

• 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…

• 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.

• 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…

• 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…
