As long a teacher of collaborative pianists, I have been most concerned in this pandemic about the current lack of successful solutions for partnering singers. I have searched carefully for technology that really works and 4D Piano is the only solution I have found. Amazingly, it is the answer for our current desperation, but it is a superior solution for all times. Invented by a superb pianist, Lucas Wong, whom I have known well for some years as a versatile performer and teacher in solo, chamber, song, and operatic repertoire, 4D Piano not only meets the needs of singers, but it trains them rhythmically, in ways we often neglect, through visual sharing of the piano part. It also trains pianists who, while not actually playing the piano, are in the same collaborative relationship at any given moment by just the movement of a finger! As the operator of 4D Piano, one can partner in ritardandi, accelerandi, and fermati as well as in leadership and sensitive following of a singer just as one would do when actually playing for the singer. There is no lag time and real and detailed ensemble is possible! Thank you, Lucas!
