The hardest part of learning anything is getting started. In learning an instrument, the task can at first seem daunting—but using this app was a easy way to ease into the most basic tool one needs to play a guitar: knowing the neck! Rob Phelps has done a characteristically fantastic job in helping to make his vast knowledge base accessible to even the newest student. I’d highly recommend this app to students who have a guitar and want to shred, but have no clue where to start. Or even those shredders who want to add a more formal knowledge of the neck to their musical repertoire. It’s a fun and creative app, and has a lot to offer.
