AcousticBrainz aims to automatically analyze the world’s music, in partnership with MusicBrainz and “provide music technology researchers and open source hackers with a massive database of information about music.” This effort is crowd sourced neatness, which means people from all over the world are contributing data by having their computer crunch through their MusicBrainz-IDed music libraries and automatically uploading all the low-level features it extracts.
I construct today’s review from low- and high-level data recently extracted from a particular music track AcousticBrainz. Can you guess what it is? What characteristics it has? (“Probabilities” are in parentheses.) The answer will be revealed below tomorrow.
Here we got a C-minor tonal (0.97) track with a tempo of 164 beats per minute. It is instrumental (0.62) and female (0.74), not danceable (0.98) but maybe a Viennese Waltz rhythm (0.52). It has an acoustic mood (0.97) and is not aggressive (0.96) and not electronic (0.72). Definitely not happy (0.98) and not party (1.0), but relaxed (0.98) and sad (0.75). It is quite likely to be electronic (1.0) ambient (0.95) jazz (0.91) classical (0.76)
It is “Nicht streb’, o Maid” from Richard Wagner’s Die Walküre (Act 3, Scene 3)! Apparently, it comes from this release.
