Partido Alto is also the name of a particular rhythm that is derived from the above-mentioned style of samba (especially in a jazz context).
Partido Alto has its origins in the religious parties in rural communities where jongo was played, a type of music very rooted in Africa, accompanied by drums called candongueiros, angumativas and caxambus.
There's a traditional jongo nucleus around the samba school Império Serrano in Rio de Janeiro, which is active to this day.
More recent musicians of the such as Grupo Fundo de Quintal, Zeca Pagodinho, Almir Guineto, Trio Calafrio and Arlindo Cruz are, among other things, exponents of the genre, although they don't restrain themselves to it.
Examples of prominent songs which can classified as partido alto are the famous "Não Vem (Assim Não Dá)", from the classic record "Quatro Grandes do Samba", where Candeia, Elton Medeiros, Nelson Cavaquinho and Guilherme de Brito share the verses, and "Perdoa", by Paulinho da Viola, where he and Elton Medeiros share the verses.
