Yamaha PSR 225 Electric Keyboard and the Blue "Magic Button":
Another factor that allows many of my arrangements to be played by young musicians is the use of what I call the “motherboard”. In order to put together a “keyboard ensemble” you can use any kind electronic keyboards you wish, BUT you do need one Yamaha PSR 225 (also known as the “motherboard”). This particular keyboard has a special feature called “smart chord”, which has chord progression sequences prerecorded into the piano. Once you identify a songs key, you set “smart chord” to the appropriate number and you’ll have complete harmonization and accompaniment by touching only one key at a time (on the left side of the keyboard). On this score, the PSR 225 is labeled as “Keyboard Harmony” or just KH. You will notice there is only one note written at a time played by this designated performer. Remember, this one note activates a complete set of harmonization’s and accompaniments that best suits the arrangement it is written for. The “smart chord” setting is activated on this Finale playback audio file. This i-Pad version matches the keyboard arrangement, but instead of the “motherboard”, i-Pads will use “smart piano”. If you are combining electric keyboards and i-Pads, either one or both may be used.
