Philadelphia Soul

en.wikipedia.org/wiki/Philly_soul

Philadelphia (or Philly) soul, sometimes called the Philadelphia Sound or Sweet Philly, is a style of soul music characterized by funk influences and lush instrumental arrangements, often featuring sweeping strings and piercing horns. The subtle sound of a glockenspiel can often be heard in the background of philly soul songs. The genre laid the groundwork for what are now considered Adult contemporary and smooth jazz by fusing the R & B rhythm sections of the 1960s with the Pop Vocal tradition, and featuring a slightly more pronounced Jazz influence in its melodic structures and arrangements.
