• create_score

  Create a score you write as a .cesure and open it as a draft, e.g. {"version":2,"score":{"title":"Song","tempo":96,"tracks":[{"name":"Guitar","instrument":"GUITAR","measures":[{"staves":[{"voices":["(0.6 2.5 2.4).2…

• import_score

  Open as a draft a score the person gives whole: a .cesure file's text, AlphaTex, or an "Open in Cesure" link. The score is taken as it is, never rewritten. A link to any other page (a video, a recording) opens nothing: Cesure reads no page.

• read_score

  Read measures from..to of a track of the draft (all by default, 200 at most a call: past them, the answer's more says where to go on) as .cesure measures — id, time signature, voices in the compact notation (second voice, hands, ties included) — with the repeat signs and tempo…

• edit_measures

  Rewrite measures from..to (numbers, inclusive) of ONE track of the draft with .cesure measures, as read_score returns them; to = from - 1 inserts before from. A measure written with its id stays that measure, even rewritten; one written without its id is a new measure, and the…

• transpose

  Shift the notes of the draft by some semitones; the placement follows, and no note keeps a wrong pitch. A note no string of its track carries at its shifted pitch goes where notesOffTheNeck says: retune_lowest_string tunes the lowest string of the track down to the lowest of…

• refinger

  Place the notes of the draft again on the neck (string and fret), keeping their pitches: mode auto, standard (lowest frets) or optimized (fewest hand moves); searchCapo lets it choose a capo.

• undo_last_change

  Give the draft back the score it held before its last change (edit_measures, transpose, refinger, or an undo): the score it holds now becomes the one before, so calling it again redoes. One step only, and only when Cesure had room to keep that score; it says so when it had not.

• search_catalog

  Search Cesure's catalog of free pieces by words of a title, a composer or both: a piece is found when each word is in one of them, a short joining word such as 'by' aside; returns title, artist, licence and link.

• open_in_cesure

  Show the draft in the Cesure player, to read and hear it. Where the host draws apps, the player plays the draft in the conversation; everywhere, the answer gives the short link that opens it in Cesure, with no account, and the score's summary.

• list_my_scores

  The scores of the person's linked Cesure account ("My scores"), the most recently changed at the top, 200 a call (offset skips that many; when there are more, the answer's more gives the next offset): id, title, when last changed, and its tags; then every tag of the account…

• read_my_score

  Open one score of the linked account as a draft, by the id list_my_scores gives: the answer is the draft and the score's summary; read_score reads its measures. Needs the account linked.

• save_new_score

  Save the draft as a NEW score in the linked account's library (never overwrites one; a free account keeps 3 scores), under a title (default the score's own). Needs the account linked.

• update_my_score

  Write the draft back over the score of the linked account's library it was opened from (read_my_score), as saving in the app does: refused, nothing overwritten, when the score was saved in Cesure since. The library keeps the score's earlier version. Needs the account linked.

• organize_my_scores

  Organize the scores of the linked account with tags, in ONE batch applied whole or not at all (at most 500 changes, counting the tags add creates): create_tags creates tags, add puts a tag on a score (creating the tag if the account has none of that name; names compare without…
