Pitch Yarn of Matter (PYM) is a synthpop project by Brazilian electronic musician Marcelo Gallo that released two studio albums in the 1990s as well as a number of tracks that found their way onto electronic music compilations.

In 1994, during a tour of the German band Second Decay, Michael Budde, propriator of the Subtronic record label invited PYM to record their first album in Germany, making PYM the first Brazilian synthpop band to appear on the international market. In 1996, Marcelo Gallo decided to put the project to rest in order to be able to concentrate fully on his other project, Nude.

Influences include Gary Numan, Depeche Mode, Ultravox and others. Read more on Last.fm. User-contributed text is available under the Creative Commons By-SA License; additional terms may apply.
