indie music isnt a difinite style of music, but most indie bands are influenced by each other causing a similar sound. the sound is melodic, the instruments are simple but well textured. usually includes a simple but origanal guitar riff, another guitar riff layered to complement it, bass doing the same, simple drum beat (but fitting the song well) either a keyboard or violin or something to bring out the underlying melody, and soft vocals, usually well harmonized.
