Standard guitar tunings usually defines the string pitches as E, A, D, G, B, and E,from lowest (low E) to highest (high E). There are however various kinds of non-standard tunings called “alternative" or “alternate" tunings. Recently, some alternate tunings haveattracted the attention of schools and music therapy since they make it easier for a player to accompany simple songs. Based on the same interest, I devised an alternate tuning which allows the playing of both major and minor triads by only barre fingering. I believe this particular tuning has not yet been employed. This thesis outlines this alternate tuning I devised and offers various supporting methodology. I think the employment of this tuning is a good way for beginners of guitar to accompany simple songs.
