I purchased this product January when I bought a keyboard and realised I would not be able to progress on my own. I had piano lessons for many years as a child – reluctantly – and so I did have a few basics that my laziness in the past had stopped me from really mastering reading music. Playground sessions has enabled me to fill in all the gaps. I am thrilled with the progress I have made in just a month. I have become a piano addict thanks to this program. I am 60 years old and I know people complain they find things more difficult to learn as they get older time finding this a total pleasure. I look forward to spending countless hours with my keyboard and playground sessions.
