Note returns Pitch in Hz #8

Open charneykaye opened 8 years ago

charneykaye commented 8 years ago

Any note (with a pitch class + octave) ought to be able to return a Pitch.

Allow for future selection of different tunings.

See jFugue for an example of a pitch algorithm

There would be a configuration for master tune as well, e.g. 440Hz vs. 432Hz

Hi,

Not sure if I understand. Does this means that I can pass, say C#3 as a single note or as a scale/chord, and get its pitch value in Hz? Because that would be really useful when working with other tools (Supercollider).

Yes!! That's exactly the feature I imagine. There would be a configuration for master tune as well, e.g. 440Hz vs. 432Hz

Following #28 there are two additional enhancements I'd like to see before we mark this issue closed:

As in Scientific Pitch Notation and also embracing other tuning, as in Scientific Pitch, e.g. Verdi's 432Hz for A4, instead of 440Hz.
Consideration of note as either one or two arguments, such that either of these is well-formed: music-theory pitch A 4 or music-theory pitch A4

Here's an example of both of these enhancements in action:
