Our Pianos Personal Checks feature several pictures of the classic ebony and ivory piano keys and a baby grand piano. Known as the ‘King of Instruments,’ the piano is the most versatile and interesting of instruments. It has the broadest note range and the ability to play not just melody but accompaniment as well, all at the same time. A little fact you may not be aware of is that the piano is actually classified as a percussion instrument. This is due to the fact that the string is hit by a hammer to produce the sound. An average piano has 230 strings with about 165 pounds of tension on each one- thus having a total tension of about 18 tons. That is a lot of tension!You have to pay to play, so why not use these Pianos Personal Checks, which are available in single and duplicate check format. Matching address labels and a coordinating checkbook cover are also available.
