I had given the random YouTube video postings a rest, but this one is so awesome that I have decided to start them up again. I sometimes let children play with my guitar as well. Open tunings are a great way to make this activity as pleasant as possible. An open tuning is an instrument tuning in which strumming the open strings will sound a chord. In standard tuning playing the six open strings of a guitar does not make a pleasant sounding chord. Guitars with nylon strings are more suitable for children than steel stung guitars.
