Steinway Alma Tadema

The sound of a Yamaha is what I would consider being “stable”. The model piano really does make a difference when comparing Steinway and Yamaha. Overall though I think you’ll find Yamaha pianos to be much brighter overall. At the same time, you’ll find Steinway to be a more creative instrument to play with.

The Top 10 Best Piano Brands In The World

• C. Bechstein.
• Blüthner.
• Bösendorfer.
• FAZIOLI.
• Grotrian.
• Sauter.
• Shigeru Kawai.
• Steinway & Sons (Hamburg)

First of all, Steinways are created to be the finest pianos possible. They are made with the best materials with highly skilled labor and have a long, rich history of piano manufacturing. There are a number of piano companies mostly in Germany, that make pianos on an extremely high level and cost as much as Steinway.

To help you out, I’ve surveyed Sweetwater’s current selection of digital pianos and compiled a list of keyboards with the most realistic piano sounds.

• Kawai MP11SE.
• Roland RD-2000.
• Nord Grand.
• Dexibell Vivo S7 Pro.
• Korg Grandstage 88.
• Kurzweil Forte.

The average price to tune a piano ranges from $65 to $225, and the cost can increase by several hundred dollars if the piano requires multiple tuning sessions or repairs. Piano tuning is a skill that only experienced professionals should do.

A new piano, or a piano 10, 15 or 20 years old that has never been serviced needs tuning three or four times before stabilizing. The only exception is when a new piano has been sitting on the showroom floor for several months and has gone through several in-house, or showroom tunings before purchased.
