With so many kids and so many schedules, it was hard to fit in piano practice until we got these keyboards and use them in the car on the way to activities. Some of the kids enjoy the feature that lights up correct notes to play a song. The melody plays the correct note no matter what key is hit. It is nice that wrong notes aren't being heard, only the melody being learned, but I WISH THAT THE PIANO WOULD NOT SOUND THE CORRECT NOTE UNTIL THE CHILD ACTUALLY PLAYS THAT NOTE. The piano could just be silent if the student played the wrong note until he found the right one. The kids quickly realized they could play a song by just hitting one key over and over. Friends have seen us using these in the car and gotten one for themselves.
