It sounds like new music is beating to a new rhythm, outside the drum (box). Here's an excerpt. Note the last sentence. Now there's a conversation starter!
New classical music is in a period of unpredictability. For much of the 20th century there was the ''right'' sort of music to compose, especially within the classical world. If a composer wanted to write a new string quartet, for example, it needed to be of a certain musical language to be taken seriously by the musical establishment.
The exciting thing about new music at the opening of the 21st century is that the barriers to music creation are breaking down. This is having a significant effect on the types of music that composers from all over the world are creating.
For a start, there are more composers writing music now than at any time in history. Numerically speaking, most of the world's composers are songwriters or electronic musicians, using the incredible growth in technology to record and disseminate their material. They need not know music theory or even how to play an instrument, as computers can facilitate incredible sound worlds in much less time than it takes to learn the clarinet.
