Research suggests that computer training for 3 year old children does not improve reasoning ability.
In my opinion, piano training should be a required part of the first four grades in elementary school. I, frankly, would start it by age 4 years.
I did start to teach my daughter at age 3.5 years but my hair turned gray in the process (the twenty or so that I have left). But I believe it was worth it and hears why.
The Los Angeles Times ran a interesting article on February 28, 1997 entitled ãStudy Finds Piano Lessons Boost Youths Reasoning.ä
In this study approximately 100 children ages 3 to 4 years were divided into four groups. One group had no training, One received individual singing lessons, one received individual computer lessons and one received individual piano lessons.
The children were tested on four tests of mental ability before and after the project. Only the group taking piano lessons showed any improvement.
