I have had absolutely no training on the piano and just a bit of understanding of music theory and I now find myself playing "sweet", as my spouse calls them, songs in 12 different keys each with a different feeling tone. 

The keyboard makes sense for the first time and I have no trouble knowing where to put my fingers. 

The hardest part is getting in touch with how I feel and playing that out. When it happens, it is so gratifying. 

Treat yourself to this!
