Bodibeat Matches Music to Heart Rate

No longer must we humans struggle to make our heart rates match the music we hope to exercise to.  Yamaha, the New York Times reports, has turned the tables and delivered an MP3 player that plays tunes in sync with our heartbeat. The paper reports that the new Bodibeat works in four modes: workout, fitness, training and a standard
music-playing mode. The mode automatically matches your music
with your heartbeat — slow down and you might get some smooth jazz;
speed up and you get grunge — while the other two modes play music at a
brisk tempo.  The amazing new machine, the Times reports, comes with a set of
electronic beats or can pull music from your own collection.
