Hmm - how can I listen to a "beat" of around 175BPM which keeps my mind to the grindstone - and not slow down uphills or slacken off when I am tired -- while at the same time listen to the music which I find to be most inspiring and uplifting ie Italian Opera????
Well - I have done it! I have overlaid a quiet metronome beat over the said Opera music (using Audacity) - and it works!!!!! Not only technologically -- but psychologically as well It must have something to do with left brain/right brain stuff, because I can "hear" the metronome beat and keep to it while at the same time "listen" to the music
Operas usually go for quite a long time - so it looks like some long runs for me
