A musical ensemble is a group of three or more musicians who gather to perform music. There are several denominations of ensembles according to their size and composition.
Poesybeat is an online collaborative artform whereby participants combine music and poetry together into a new musical style. The authors of the music and the poetry often have never met one another. The premiere site for this style is poesybeat.org, a not-for-profit site that promotes the poesybeat artform.
