![]() ![]() The sample code is here: from picoed import music Now we are able to have the custom melody played with the above formats. For example, middle “C” is 'c4' and concert “A” (440) is 'a4'. ![]() The definition and scope of an octave conform to the table listed on this page about scientific pitch notation. The opening of Beethoven's 5th Symphony would be encoded thus: ![]() The default states are octave = 4 (containing middle C) and duration = 4 (a crotchet, given the default tempo settings - see below).įor example, if 4 ticks is a crotchet, the following list is a crotchet, quaver, quaver, crotchet-based arpeggio: The octave and duration parameters are states that carry over to subsequent notes until re-specified. For example, Ab is A-flat and C# is C-sharp. If the note name R is used then it is treated as a rest (silence).Īccidentals (flats and sharps) are denoted by the b (flat - a lower case b) and # (sharp - a hash symbol). Like RPi Spy's picopins it started as a GitHub gist, you can find the history here - Changelog 1.1.For example, A1:4 refers to the note “A” in octave 1 that lasts for four ticks (a tick is an arbitrary length of time defined by a tempo setting function - see below). It somehow wasn't inspired by Raspberry Pi Spy's "picopins" which came first and solves this same problem in bash. This project was inspired by GPIO Zero's command-line pinout.
