5 music things

5 in 5

I like to cover 5 things in 5 minutes for lightning talks. Or one thing. At the local
Python user group, sometimes questions or other circumstances turn these 5
in 5 more into a 5 in 10-15...

5 Music Things

Eventually, after a year or two, I'll revisit a subject. I recently noticed that I had
not talked about music related things in almost two and a half years, so I did
5 quick Jupyter notebooks and presented that. Interestingly enough, none of
these 5 things were covered back then. The github repo includes edited versions
of the notebooks, based on the interactions at the meeting during my presentation.
Requirements: All require the following
pip install jupyter
Alphabetically...

1 - Audio

2 - libROSA

Here we will need to pip install matplotlib and numpy, and of course librosa.

3 - music21

pip install music21
You'll need some external programs: Lilypond and Musescore
You also need launch scripts for each of them. On a mac, use the provided
launch scripts in the mac/ folder of this repo. Make sure you chmod a+x them.
Change the path in the notebook to reflect your own user path.

4 - python-sonic

pip install python-sonic
You'll need one external program: Sonic Pi and to start it before running through
the notebook.

5 - pyKnon

pip install pyknon
You'll need one external program: timidity

easily installed:

  • in Linux with apt-get install timidity
  • on a Mac with brew install timidity
This was mostly an excuse to demo that external command line tools like timidity
or sox can be used here.


Have fun!

P.S.: Github repo at: https://github.com/fdion/5_music_things but for some strange reason, github will not render the first (0-StartHere) notebook. This blog post is basically that notebook, putting things in context.

Hello,

Thanks for the blog. I am trying to install librosa package on raspberry pi 3 but couldn't get any success as such. There are many threads on the internet about getting difficulties in making librosa installed on pi. Could you please share how you were able to make it work ?
