Audio & Video
Transport yourself back to ballroom dancing of the 1950s with this up tempo quickstep style.
Typically French in character, this mid tempo style is great for swing standards.
Marches are a staple of both concert and marching bands, with the American marches of John Phillips Sousa perhaps being the most widely heard. With a brass and woodwind heavy arrangement suitable to the sound of either a marching band or concert band, this style will work equally well in accompanying a Sousa march or, for example, a college fight song.
Smooth is definitely the perfect word to describe this style. Whether you use it to play jazz or pop, what you'll get is a laid back sound with sparse, tasteful drumming, bass and guitar over which you're free to play your own solos.
The disco music of the 70s is all about big speakers, big shoes, and living the high life: at heart, disco is all about celebration. And with an unmistakable treble heavy disco guitar, along with funky bass and horn lines this style is perfect for celebrating anything at all.
Some of the biggest ballads of the 60s came out of Detroit and Motown records. Detroit put a distinctive soulful pop spin on ballads in songs like “My Girl”, and “I Second That Emotion” that you can hear in this style. Using lots of backing vocals alongside prominent drums and horns, the Motown sound is unique but sounds great accompanying a wide variety of ballads.
