How it works – play through the Phrase 1 sound files, the (40) means 40 beats per minute, so slow, then try the 60 beats per minute. Once you are happy with that move on to the phrase 2 sound files, same again, 40 first then 60.
When you are reasonably happy try the phrase 1 and 2 combined files, 40 first then build up to, say 80. Then move on..
The sound files are set to loop round, so you wont have to keep clicking them to play, There are 4 beats before the music start to get yourself prepared.
