After a lifetime of pianism – I am now 73 – I am so inspired by this program. I could always play by ear, which helped me avoid the work of sight reading. I also sang, and ‘got by’ by reading intervalically, and probably also by internalized knowledge of key signatures and their translation pianistically. I wish I had known this program when studying. My “talent” made it easy, as a young person, to avoid the hard work of learning to sight read. This is a great tool, and I highly recommend it.
