The act of ivory tickling can cheer up a crowd, win over a love interest, or make a peaceful pachyderm feel significantly more like stampeding. Get your phalanges flowing with today's Groupon: for $59, you get a basic piano tuning from Ritchie on Keys (a $125 value). This Groupon is valid within a 50-mile radius of the 92026 zip code.

A professional musician with more than 30 years of experience as a concert pianist and piano tuner, Ritchie Carbajal cures clavichord ailments with a variety of tuning, regulation, voicing, and restringing services. During a basic piano tuning, Ritchie extracts disharmonious tones from worn wires, which will result in a freshly tuned piano that can finally hit all the allusive pitches of "Hot Cross Buns." Today’s Groupon applies to pianos that are being maintained on a semiregular basis and additional fees ($75/hour) may be required for raising the pitch to A-440, adjusting the action and keys for optimum performance, and for tuning pianos that haven’t been played since Mozart composed "Chopsticks."
