Voicing Cadenza S Hammers

Isaac Cadenza S Hammers have the unique capacity to flex as a function of hammer/string impact intensity. Impacting the strings causes Isaac Cadenza S Hammers to compress building up the internal resistance which must release to lift the string returning to it the frequencies damped out by the impact. This second lifting of the strings by the compression release approximates a tennis ball rebounding off a wall.
The hammer/string impact provides the decibel level. The second lifting of the string by the unique flexing of Isaac Cadenza S Hammers is the last event before the hammer leaves the strings and it provides the musical character of the note.

Isaac Cadenza S Hammers are voiced by adjusting the amount of flexing appropriate to the individual piano. To limit the flexing of the hammers the shoulders are reinforced by applying a hardener. The most effective hardener for Isaac Cadenza S Hammers is our quick drying Toneplus Plexiglass and Acetone Solution.

To increase the hammer flexing, the felt between the molding and the outside of the hammer is softened up by sticking a single needle right through the flat side of the hammer, so the point of the needle is seen on the opposite side. The area immediately above the molding or next to the molding at shoulder level is softened by 5/6 stitches.

Isaac Cadenza S Hammers will stay at their voiced level. No need to revoice.

...."Wow! Honestly Ari, I have never heard such a difference made in a piano before. In the words of my client: "you made my tin can sound like a Bosendorfer." Thank you!

...."When I use Isaac bass strings and hammers in conjunction with my new physically crowned sound boards, the vibrancy of the tone is phenomenal.  The pianos seem to come literally to life.  The sound is just like a living presence in the room."
