Larry Weiss has been a Registered Craftsman Member of the Piano Technicians Guild, servicing the Miami-Dade and South Broward areas since 1975. Larry is a master piano tuner technician and offers professional quality rebuilding, restoration, and concert piano preparation. Over the years he and his brother Barry Weiss have restored thousands of pianos back to being fine quality instruments. Quality and integrity is our number one goal.


Tuning is creating a equal tempered scale, tuning all unisons and octaves pure so all the intervals sound proper and clean when music is played. Piano manufactures recommend that you have your piano tuned every six months to maintain the proper tension on the strings and to keep it at concert pitch. When neglected the stings will drop in pitch and the piano will become out of tune.


Voicing is done to change the quality of the tone. This is done by softening or hardening the hammers. We can make a piano more mellow or bright depending on the pianist personal preference. The trade off with a very soft voicing is loss of volume which can make other action mechanical noises more apparent. The trade off on a very bright piano is the loss of playing very softly with control, distortion of sound when played loud and it is harder on the tuning. We are happy to discuss any of your questions and concerns when we evaluate your piano.

Action Regulation

Action Regulation restores the piano action back to factory specifications. This brings back an even touch, gives the pianist control and increases repetition. Every piano is unique and some require regulation more often than others. But a good regulation can last for many years.

Your piano is made primarily of wood, a versatile and beautiful material ideal for piano construction. However, being made of wood, your piano is greatly affected by humidity. Seasonal and even daily changes in humidity cause wood parts to swell and shrink, affecting tuning stability and touch. Extreme swings in humidity can eventually cause wood to crack and glue joints to fail.

Other materials in your piano also are affected by changes in moisture content in the air. The many felt and leather parts in your piano’s action can change dimension, affecting regulation and friction, or stiffness of the touch. Very high humidity can even create condensation on metal parts such as strings, tuning pins and hardware, eventually causing them to rust.
