Old school hip hop is noted for its relatively simple rapping techniques compared to later hip-hop music.Artists such as Melle Mel would use relatively few syllables per bar of music,with relatively simple rhythms.

Much of the subject matter of old school hip hop centers around partying and having a good time.One notable exception is the song "The Message", which was written by Melle Mel for his hip hop group, Grandmaster Flash and The Furious Five. Immortal Technique explains how party content played a big part in old school hip hop, in the book How to Rap: 

"hip-hop was born in an era of social turmoil... in the same way that slaves used to sing songs on a plantation... that's the party songs that we used to have".
