My son has joined the Yamaha children electone course recently and now is now learning organ. This course is held at a studio at community centre and not at Yamaha school itself. The course is about $150 for 12 lessons. When I asked the teacher about home practise, she asked me to get a Yamaha organ. But during the 'trial lesson' the Yamaha staff actually said getting a keyboard is enough for beginners. Actually it seems like piano class is more popular than organ. I am still not sure if let him stick to organ or switch to piano later. My purpose is expose him to music/musical instrument so he can enjoy music better. So far he seems to enjoy the group class 'cos of company. Can anyone tell me why they choose piano over organ? Or where can I get a reasonably priced organ?
