My piano hadn't been tuned in years and was very badly out of tune. Calvin did a wonderful job tuning it, and also provided clear information on the condition of the piano relating to its sound and action. I will be using his services again, and highly recommend him!

Calvin Robertson showed up on time and went right to work, and my piano never sounded better! He finished the job with a concert-quality rendition of “Total Praise,” one of my favorite songs. He’s definitely the guy I’ll turn to the next time my upright needs a tuning.

Mr. Calvin took two hours to both fix the pitch of my piano and tune it. Hearing him play it when he was done filled my house with beautiful music. He also helped me see what was needed and why. Money well spent. I highly recommend him.
