So what is this R&B you speak of?

Rhythm and blues is always cut down to plain and simple R&B!

It's characterized by a
strong backbeat and repeated
variations on syncopated
instrumental phrases.

This genre of music is very popular with people of Afro-Caribbean decent. It was created by African Americans in New orleans during the 40's. R&B originates from Jazz, Blues and good old Gospel , moreover you can still hear a hint of each genre in especiaily in songs by Mariah Carey and Mary J. Blige.

Until 30 years ago Rhythm and blues bands usually consisted of piano, one or two
guitars, bass, drums, and sax.

However since the 1980s, a
newer style of R&B developed,
becoming known as 'contemporary R&B' which is a newer version of soul and funk that is influenced pop music.

Typical elements now used are:
Synthesizers, Keyboard, Drum
machine,Synclavier, sample loop,
triplet swing and rapped vocal parts.

A good example of a contemporary R&B song is Alicia keys - No one:

The majority of songs under this genre are to do with relationships and are often very sexual. However it isnt as harsh and gritty as hip hop!
