Swiss born musician Christian Zehnder uses the Alps as his soundboard as searches for the perfect echo. The avid climber knows his echoes well and has a vocabulary for their differences like I’ve never heard.
If you haven’t had the simple pleasure of belting out a few random notes up in a box canyon just to hear what comes back, I highly suggest you get out there and try.
p.s. this microphone is terrifying: 
…definitely cracked a smile when he put on the wind protection 💨
