Musicmap ~ Genealogy & History Of Music Genres


Musicmap attempts to provide the ultimate genealogy of popular music genres, including their relations and history. It is the result of more than seven years of research with over 200 listed sources and cross examination of many other visual genealogies. Its aim is to focus on the delicate balance between comprehensibility, accuracy and accessibility. In other words: the ideal genealogy is not only complete and correct, but also easy to understand despite its complexity. This is a utopian balance that can never be achieved but only approached. By choosing the right amount of genres, determining forms of hierarchy and analogy and ordering everything in a logical but authentic manner, a satisfactory balance can be obtained. Said balance is always the main subject of discussion in music genre genealogies and the capital reason why an absolute visual reference has been absent thus far (and probably always will be). Musicmap is a platform in search for the perfect balance of popular music genres to provide a powerful tool for educational means or a complementary framework in the field of music metadata and automatic taxonomy.

Cover Art Archive ~ Online Artwork Library


The Cover Art Archive is a joint project between the Internet Archive and MusicBrainz, whose goal is to make cover art images available to everyone on the Internet in an organised and convenient way.

Images in the archive are curated by the MusicBrainz community and go through a peer review process to ensure that they are correct, free of spam and of the best quality. If you would like to contribute cover art, create a MusicBrainz account and follow the guide. To see what has been added to the archive recently, please see the Cover Art Archive page at the Internet Archive.

MusicBrainz also provides API documentation for retrieving cover art via a release MBID. A C based client library libcoverart is available as well as the Java coverartarchive-api library.

OpenAIR Library ~ Open Acoustic Impulse Responses


Reverberation is an audible effect that is heard every day as a result of sound interacting with the environment around the listener. It is an effect that is commonly added artificially to electronically recorded and produced music, as well as in other media such as cinema, virtual reality applications and computer games. Auralization is an increasingly popular technique for accurately simulating reverberation and this website supports this practice through an expanding library of downloadable acoustic impulse responses (IRs) from interesting buildings, spaces and other sources.

The aim of the Open Acoustic Impulse Response (Open AIR) Library is to provide a centralized, feature rich and future proof on-line resource for anyone interested in auralization and acoustical impulse response data. For example it may be useful for researchers to quickly compare impulse responses recorded using different approaches, for developers of game audio wanting to recreate the acoustic environment of a specific building, or for musical composers looking for a desirable reverberation effect.
