YAMAHA DIGITAL PIANOS
Before starting a demonstration on a Clavinova we are often asked, "Why would you purchase a digital piano in preference to an acoustic piano?" I believe the answer to that depends very much on the individual needs and means of the customer.
As one of Australia's oldest family piano businesses we certainly do not want to convert every piano buyer to a digital piano. Far from it. However we believe the day of the old second hand piano with the uneven touch and dicey pitch is not the way to train or inspire anyone. For a similar price to many of these old suspect instruments, you can purchase a new digital piano with correct pitch and touch.
Many are also equipped with internal digital recorders, enabling the student to check their performance, digital metronomes to practice timing, USB for computer compatibility and headphone outlets for silent practice. Add to that the lack of maintenance costs (no tuning required) and they start to look very viable.
As a former professional musician and music teacher, I consider a good digital piano to be a valuable teaching aid that could be used exclusively up until grade six, at which stage I would advise the purchase of a quality professional acoustic piano. A caution to the buyer (usually Mum and Dad), be prepared to own two pianos. I doubt the student will let you part with their digital.
Now that you are thinking this may be the way to go the next decision is, "Which brand?"
Yamaha has certainly been at the leading edge of electronic music for decades, but they have also made approximately six million acoustic pianos. Most of their competitors are new at one or the other and struggle to produce all facets of a good digital at a reasonable price. The world has made Yamaha number one for touch, tone, reliability, value for money and useability.
