analyze-intervals clj

(analyze-intervals chord)

Creates an interval list from a pch chord

cents->scaler clj

(cents->scaler cents)

Converts the cents into a scaler value 2^(cents/1200).

Translated from Common Music.

hertz clj

(hertz a)

General function for converting value a to frequency. It will convert keywords, MIDI note numbers, PCH, strings, and symbols.

invert clj

(invert [base-pch & more :as pchs] inversion)

Inverts a list of pchs given the version number

keynum clj

(keynum a)

General function for converting value a to MIDI notenumber. It will convert keywords, PCH, strings, and symbols, and return any other value. Assumes PCH is 12 TET with [8 0] as Middle-C (MIDI Note 60).

keyword->freq clj

(keyword->freq sym)

Convert keyword or symbol to frequency (i.e. :A4 is 440.0)

keyword->notenum clj

(keyword->notenum sym)

Converts keyword or symbol to MIDI notenum (i.e. :C4 is 60, :Cs4 is 61)

midi->freq clj

(midi->freq notenum)

Convert MIDI Note number to frequency in hertz

pch->freq clj

(pch->freq pch)

Converts PCH to frequency. [8 0] is equivalent to Middle-C (MIDI Note 60), which is equivalent to :C4. Assumes 12 scale degrees per octave (12 TET).

pch->notenum clj

(pch->notenum pch)

(pch->notenum [oct scale-degree] scale-degrees)

Converts PCH notation to note number. Optional number of scale degrees per octave, defaults to 12.

pch->sco clj

(pch->sco [a b])

Converts PCH notation to Csound-style pch string.

pch-add clj

(pch-add pch interval)

(pch-add pch interval scale-degrees)

Add interval to pch (i.e. [8 0] 11 => [8 11]). Defaults to 12-tone octave.

pch-diff clj

(pch-diff pch1 pch2)

(pch-diff pch1 pch2 scale-degrees)

Return the interval between two pitches (i.e. [8 0] [9 1] => 13). Defaults to 12-tone octave.

pch-interval-sco clj

(pch-interval-sco pch intervals)

(pch-interval-sco pch intervals scale-degrees)

Given a base PCH pch and sequence of intervals x, generates a sequence of Csound pch strings. For example, (pch-interval-seq [8 0] [1 -2]) will yield ("8.0" "8.01" "7.11").

pch-interval-seq clj

(pch-interval-seq pch x)

(pch-interval-seq pch x scale-degrees)

Given a base PCH pch and sequence of intervals x, generates a sequence of PCH's. For example, (pch-interval-seq [8 0] [1 -2]) will yield ([8 0] [8 1] [7 11]).

scaler->cents clj

(scaler->cents scalar)

Converts a scaler into a cents value 1200*log2(ratio).

Translated from Common Music.

str->freq clj

(str->freq sym)

Convert string to frequency (i.e. "A4" is 440.0)

str->notenum clj

(str->notenum sym)

Converts string to MIDI notenum (i.e. "C4" is 60, "Cs4" is 61)

sym->freq clj

(sym->freq sym)

Convert keyword or symbol to frequency (i.e. :A4 is 440.0)

sym->notenum clj

(sym->notenum sym)

Converts keyword or symbol to MIDI notenum (i.e. :C4 is 60, :C#4 is 61).
