Music is humanity's universal language, narrowly beating out such close contenders as Esperanto, The Simpsons references, and yodelled profanity. Maintain the abilitity to rhythmically communicate across cultures with today’s Groupon: for $59, you get a piano-tuning service from Rob Cosh Piano Tuning (a $120 value). Today’s deal is valid for service areas within 50 kilometres of Ottawa’s city centre.

Rob Cosh Piano Tuning’s eponymous owner and sonic guru coaxes sweet sounds from fatigued keys with meticulous piano-tuning services. Rob carefully unseals the lids of ticklish pianos in order to adjust the pitch of strings frazzled from being plucked by confused harpists. Once the musical endoskeletons have been recalibrated, Rob conducts a complimentary inspection bolstered by any minor repairs or adjustments that can be performed within a 15-minute window. Before galloping off into a Beethoven-scored sunset, Rob vacuums piano interiors to evict dust buildups and provide a clean space to store powdered wigs between recitals.
