Looks like this chip simply picks up volume. If it's installed within the metronome, the ticking would probably be the most prominent noise. (so other noises couldn't accidentally trigger it) Then measure the timing between peaks. And maybe have the code wait for x amount of ticks to make sure it's not triggered simply by scrolling through speeds.
And then just trigger a relay with the elecromagnet.
I just wired up an ESP8266 with a https://www.amazon.com/gp/product/B00XT0PH10/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 sound detector. This is currently taped to my wireless doorbell chime. When the bell rings, the ESP8266 publishes to an MQTT topic. Node Red is subbed to that topic and fires an HTTP request (GET) to MotionEye running in a docker container. This grabs the most recent snapshot image from an IP cam on the front porch and attached it to an email sent to me.
