From birth, our daughter has gone to sleep to a rather untraditional lullaby, Ambient 1: Music for Airports, composed by the brilliant Brian Eno. The four pieces are ‘evolving soundscapes’ designed to approximate the emotional effect of visual art. To us they always have felt like the soundtrack to an amazing dream. We love it. -> iTunes.
Another wonderful creation of Eno’s (in collaboration with musician & software designer Peter Chilvers) is an iPhone app called Bloom. By echoing back patterns you create with simple taps on the screen, you’re able to produce lovely ambient melodies. Most definitely something for every age. Available on iTunes.
