Purple Rhapsody is instrumental music - 'emotions without words' is the tagline and that's what it's about.
There isn't any one constant that defines the style of a piece of Purple Rhapsody music. Every track is instrumental but the style ranges from simple piano solos through to full blown orchestral soundtracks with varying amounts of guitar (electric and acoustic), bass, synthesisers, and anything else that fits into the mix.
Recently Terry Robinson, the composer and performer behind Purple Rhapsody, worked on the soundtrack to a horror documentary called Screamer: The Art Of Terror - keep an eye out for it at a film festival near you!
There are many Purple Rhapsody albums available to buy from iTunes, Amazon, etc and physical CDs are also available from CD Baby and the Purple Rhapsody site (http://purplerhapsody.co.uk).
Please get in touch if you have a need for original instrumental music for your film project, I'll be more than happy to discuss what I can do for you.
