Re: music-pitch

[Hans Höglund]

Sounds great,

Considering scales, I think the important thing is have an indexing function analogous to list indexing, i.e. something like:

(!) :: Scale -> Integer -> Pitch

That would allow you to define a melody as a sequence of steps and map them into a mode. Obviously you could do these things on both lists and sets, as long as the pitch type is ordered.

As you can see my tuning code is just stubs, so you are free to design something from the ground up.

My only concern is that it is parametric over the input type (i.e. you can use it with both Music.Pitch.Common.Pitch and other types whenever it makes sense, for example if we add pentatonic scales). You probably want to use the types in Music.Pitch.Absolute to represent absolute frequencies.

Let me know what you come up with.

Cheers,

Hans

Hi

Excellent, thanks. I'm definitely still thinking about ways to tidy it
up / make the implementation more elegant.

Along with that, I'm planning some work on scale types [not sure if they
should be lists or sets]and also the beginnings of the tuning
infrastructure.

thanks,
Edward

Hi Edward,

I just merged your changes to music-pitch. If you want to stay in sync with the official repo just do

git remote add official g...@github.com:music-suite/music-pitch.git

git fetch official

git merge remotes/official/master

I had to make some changes to make it compile, see the commit messages. Still a bit of clean-up needed.

Regards,

Hans
