Using machine learning to spur human creativity is so 2018! Watson has used a combination of reinforcement learning and neural networks to create the Watson Beat.
- a simple 10-20 second melody file in midi format
- parameters for the creativity engine
- Several layers of music in midi format that Watson created using your input as inspiration
This repo, is all the code for the The Watson Beat. It all runs locally using
the terminal. To run it, there are a few things you need set up on your local computer first, like python 🐍!,
and a basic familiarity with git
.
Here are some directions to get your machine set up to run code, or just google it! You will also need to copy this code repository to your computer.
To get the code on your computer you will need to git clone
this repo.
Here is some great documentation on git for new comers.
Also, if you want to make contributions to the code base, we are very willing to review
merge requests (see forking).
All pull requests and commits to branches intended for release must acknowledge the

So, you just spent half an hour setting your machine up for python, and I'm telling you there is more set-up?
Yep! Welcome to the wonderful world of code. Open your terminal, and navigate to the directory you
created with your git clone
command. If you do an ls
you should see this file, README.md
, and the
specfic python requirements for this project are in requirements.txt
.
You can install the specific python packages you need for your
Watson Beat Client with the following command (again, make sure you are in this directory):
pip install -r requirements.txt
There are two main ingredients to prepare to create your song with The Watson Beat. First, you need a midi file with a simple melody. Best results come when you keep this short, about 10 seconds. Also, leave some space between your notes to give the creativity engine some wiggle room.
The second ingredient is the ini
file. The ini
file give the creativity engine all of the spices
to use, including time signature, "mood," and tempo. Read this to learn more about ini files.
Usage:
usage: wbDev.py [-h] [-i INIFILE] [-m MIDIFILEPATH] [-o OUTPUTPATH] [-u]
optional arguments:
-h show this help message and exit
-i INIFILE Store the ini File
-m MIDIFILEPATH Midi File Path
-o OUTPUTPATH Path were all the output mid files are stored (default ./output/)
-u usage
To run, clone this git project in your filesystem if you haven't already. Open a terminal window, navigate to the
project home $WB_HOME
(for example, this might be /Users/Moe/watson-beat
)
cd $WB_HOME/src
Now, in the current working directory, there is a python script that will call the code, wbDev.py
with the
parameters you pass it. To get help, just pass it the -h
flag:
python wbDev.py -h
If you pass it no paramaters,
python wbDev.py
it will use the default Ini file $WB_HOME/src/Ini/Space.ini
, the default midi
file $WB_HOME/src/Midi/mary.mid
, and output all the files to ./output/
To pass in specific midi and ini files use the following syntax:
python wbDev.py -i Ini/ReggaePop.ini -m Midi/mary.mid -o /Users/Moe/midifiles/
This is where you get to have some fun! Now, you have a set of midi files, you can use your favorite audio tools to apply virtual instruments to the sections and mix them together into a song.
HAPPY COMPOSING!
