Update: Company loaning pianos to those afffected by the tornado!

June 4, 2014. Richard Deutsch, owner of Piano Kraft in Little Rock, joined forces with Yamaha Corporation of America to provide $36,000 worth of Clavinova digital pianos on loan for a year to churches and schools in the tornado-ravaged areas of Mayflower and Vilonia. Story here:.Log Cabin Democrat news story

Massive tornado  crossed I-40 last night at Mayflower 9
 miles south of Conway and tore through Vilonia.



Devastating. Much loss of life and property. Our prayers go out to the families in all areas affected especially Vilonia (pictured above) which was also hit in 2011.

Oldest extant piano Bartolomeo Cristofori

I took this photo in 1997 at the Metropolitan Museum of Art.

Dongsok Shin performs the Sonata in d minor, K.9 by Domenico Scarlatti (1685-1757) on the earliest known surviving piano, made by the instrument's inventor, Bartolomeo Cristofori (1655-1731), in Florence, 1720. Scarlatti's keyboard compositions were performed on both the harpsichord and the early piano.

My favorite piano tech tools: Damper Underlever Jig.

Damper Underlever Jig and Damper Bean Bag  

Supporting grand damper underlevers on a rigid, straight fixture during damper installation is the best way to ensure a perfectly even lever height. That in turn allows uniform damper lift with the pedal and the keys, even sostenuto operation, and accurate damper stop rail adjustment. This jig does the job beautifully, with simple knurled brass height adjusters and a clean, functional design.

More piano moving slapstick!


What have you done lately about the Digital Behemoth?

That piano technicians endure in the face of continuous assault upon market share by the Digital Behemoth, is probably due to the fact that we remain a recognized industry in our own right. This is due primarily to the Piano Technicians Guild. Even though some of us are not members, all techs reap the benefits of the PTG's organizational presence within the music industry and in local communities far and wide as well. But more has to be done. Even with the efforts of the PTG, our industry cannot withstand the digital onslaught forever. To this end, consumer education is needed. Don't count on dealers and manufacturers to do this. Indeed, many  have a vested interest in the continued success of the digital. To educate the public on the benefits of the piano and the disadvantages of the digital is our job.
