I'm the Director of Developer Community at The Echo Nest, a research-focused music intelligence startup that provides music information services to developers and partners through a data mining and machine listening platform. I am especially interested in hybrid music recommenders and using visualizations to aid music discovery.

The World’s First MachineLearning-enabled musical keyboard !?!

Today Amazon released AWS DeepComposer which is a keyboard that will let you “create a melody that will transform into a completely original song in seconds”.

To me it looks like an Arturia Keystep knock-off.  I’m still puzzling over whether or not there’s any special ML-related features – or is it just a MIDI keyboard that comes with some AWS credits. Anyone with any insights, please let me know.

Music Machinery Chapter 2

I’ve spent the last 15 or so years thinking mostly about the machinery that gets music from the bits in an audio recording into the ears of a listener. There are dozens of examples of tools for music discovery, organization and listening in the sidebar at the right on this blog.  But lately I’ve been thinking quite a bit more about the machinery that goes into getting the bits into an audio recording in the first place.  I’m particularly interested in two aspects of this:  (1) music synthesis – the machinery that can create the sounds from scratch and (2) generative music – machinery that can generate the music from scratch.

If you are interested in synthesis and generative music, feel free to follow along in Music Machinery Chapter 2. I’m a newbie at it all so pointers and guidance will be greatly appreciated.

Smarter Playlists – My Top Tracks

I’ve just added a new Smarter Playlists component called My Top Tracks. This track source will generate a list of the top 50 tracks from your recent listening history.  You can choose from 3 different time ranges:

  • short term – the last month or so
  • medium term – the last half year or so
  • long term – the last several years

The component configuration looks like this:

Here’s an example program using the new component to surface up tracks that I’ve listened to a lot in the past that haven’t been getting a lot of play time in the last half-year.

Feel free to try out the new component and send me feedback via the google group.

update – to use the new component, you will need to logout and then log back into SmarterPlaylists to grant it the extra permissions it needs to read your recent play history.

Most popular SmarterPlaylists components

As of this morning, there have been 1,363 SmarterPlaylist programs written.   Currently there are 300 SmarterPlaylist jobs running periodically.  I was wondering what were the most popular components, so I took inventory by looking at all of those 1,363 programs to see which components were used the most often.  Here’s the list:

The big surprises for me were to see how often the Echo Nest Artist and Genre radio are being used, and even after being around for only a week, how often the RelativeDatedSpotifyPlaylist is being used.
