Comfort is a result of connection and a sense of synchronicity towards ones environment. Beatmatching the Heartbeat is one approach to accomplish this.
When it comes to DJing, connecting with the crowd is essential and absolutely necessary in order to have a good time together as opposed to just playing my stuff to people who don’t care. One major way I connect to my crowd is through rhythm by beat matching my tracks to my crowd’s heartbeat BPM.
Human heartbeat ranges roughly between 60 (resting) and 140 (heavy exercise, dancing like crazy) beats per minute (BPM). It’s not a coincidence that the BPM of music genres which compliment these states have a very similar BPM.
In the early evening, when the venue is half empty while everybody is sitting and drinking, the average heartbeat-BPM of the crowd will be somewhere around 80-90 BPM. I beatmatch the heratbeat and connect to that level. I believe raising the energy and heart beat rate in the room happens by selecting the right tracks at that tempo and obviously mixing them properly as opposed to just playing a 125 BPM house set and hoping people will catch up eventually.
When my track selection is right, I will see the energy in the room and the average heartbeat rising. That’s when I push the tempo and bring it up a notch.
It seems to be obvious common sense but real life experience shows it’s not: In order to jive together we need to adjust to our partner’s (crowd’s) rhythm (heartbeat).
