This function exists to resolve enharmonic equivalences between different spellings for the same pitch (e.g. C♯ vs D♭), and is primarily useful when producing human-readable outputs (e.g. plotting) for pitch content. Note names are decided by the following rules: 1. If the tonic of the key has an accidental (sharp or flat), that accidental will be used consistently for all notes. 2. If the tonic does not have an accidental, accidentals will be inferred to minimize the total number used for diatonic scale degrees. 3. If there is a tie (e.g., in the case of C:maj vs A:min), sharps will be preferred. Parameters ---------- key : string Must be in the form TONIC:key. Tonic must be upper case (``CDEFGAB``), key must be lower-case (``maj`` or ``min``). Single accidentals (``b!♭`` for flat, or ``#♯`` for sharp) are supported. Examples: ``C:maj, Db:min, A♭:min``. unicode : bool If ``True`` (default), use Unicode symbols (♯𝄪♭𝄫)for accidentals. If ``False``, Unicode symbols will be mapped to low-order ASCII representations:: ♯ -> #, 𝄪 -> ##, ♭ -> b, 𝄫 -> bb Returns ------- notes : list ``notes[k]`` is the name for semitone ``k`` (starting from C) under the given key.

This function is primarily intended as a utility routine for Functional Just System (FJS) notation conversions. This function does not assume the "circle of fifths" or equal temperament, so 12 fifths will not generally produce a note of the same pitch class due to the accumulation of accidentals. Parameters ---------- unison : str The name of the starting (unison) note, e.g., 'C' or 'Bb'. Unicode accidentals are supported. fifths : integer The number of perfect fifths to deviate from unison. unicode : bool If ``True`` (default), use Unicode symbols (♯𝄪♭𝄫)for accidentals.

See https://misotanni.github.io/fjs/en/index.html for a thorough overview of the FJS notation system, and the examples below. FJS conversion works by identifying a Pythagorean interval which is within a specified tolerance of the target interval, which provides the core note name. If the interval is derived from ratios other than perfect fifths, then the remaining factors are encoded as superscripts for otonal (increasing) intervals and subscripts for utonal (decreasing) intervals. Parameters ---------- interval : float > 0 or iterable of floats A (just) interval to notate in FJS. unison : str The name of the unison note (corresponding to `interval=1`). tolerance : float The tolerance threshold for identifying the core note name. unicode : bool If ``True`` (default), use Unicode symbols (♯𝄪♭𝄫)for accidentals, and superscripts/subscripts for otonal and utonal accidentals. If ``False``, accidentals will be encoded as low-order ASCII representations:: ♯ -> #, 𝄪 -> ##, ♭ -> b, 𝄫 -> bb Otonal and utonal accidentals will be denoted by `^##` and `_##` respectively (see examples below). Raises ------ ParameterError If the provided interval is not positive If the provided interval cannot be identified with a just intonation prime factorization. Returns ------- note_fjs : str or np.ndarray(dtype=str) The interval(s) relative to the given unison in FJS notation. Examples -------- Pythagorean intervals appear as expected, with no otonal or utonal extensions: >>> librosa.interval_to_fjs(3/2, unison='C') 'G' >>> librosa.interval_to_fjs(4/3, unison='F') 'B♭' A ptolemaic major third will appear with an otonal '5': >>> librosa.interval_to_fjs(5/4, unison='A') 'C♯⁵' And a ptolemaic minor third will appear with utonal '5': >>> librosa.interval_to_fjs(6/5, unison='A') 'C₅' More complex intervals will have compound accidentals. For example: >>> librosa.interval_to_fjs(25/14, unison='F#') 'E²⁵₇' >>> librosa.interval_to_fjs(25/14, unison='F#', unicode=False) 'E^25_7' Array inputs are also supported: >>> librosa.interval_to_fjs([3/2, 4/3, 5/3]) array(['G', 'F', 'A⁵'], dtype='.cs$g|]}|dkr||qSrr"rrr"r&rJs z#interval_to_fjs..cs&g|]}|dkr|| qSrr"rrr"r&rJs rBrr^_) rrrrrr*ZaroundKeyErrorprodrF SUPER_TRANS SUB_TRANS) rr|rrAr}Z note_nameZ interval_bexcZotonalZutonalsuffixr"rr&ros,Z " )4__doc__renumpyr*ZnumbarZ intervalsr_cacherZutil.exceptionsrtypingrr r r Zutil.decoratorsr Z_typingr rr__all__r{r+ enumerater8compilerrpr7ZndarrayrrrboolrrrrrrrrrrOrrfloatrsetr"r"r"r&sv      JSb !.8Z
