Learn my method for quickly detecting the pattern...quickly finding the key, so you can just start playing! In this example, we go after the songs Sweet Caroline, by Neil Diamond, Photograph, by Ed Sheeran and Something, by the Beatles. If you can't walk right up to any song and just start playing along within milliseconds...you NEED this insight. It's not the realm of geniuses...there is a simple method to the madness that ANYONE can learn very quickly.
