BUY IT NOW in my eBay Store: GUITARSLIDERULE If you were to choose a key, then chart every note in that key on the neck, you would see 5 distinct hand positions. The REQUINTO SLIDE RULE CHART is an 8.5"x 11" laminated chart showing the 5 POSITIONS in every key over printed requinto necks. The tuning is A-D-G-C-E-A. The brown dots are at the 5th, 7th, 12th, 17th and 19th frets. Easy to use. For instance, above each set of 2 fretboards are 4 related keys. The area on the end are the open strings. If the first chord of a song is C Major, like the chords: C Am F and G, improvise using C Major fretboards or C Major/m7 fretboards. Usually, the first chord indicates the key. If the chords of a song begin in Em, use the fretboards for E minor or E minor/Maj6. Every note showing would be in that key along with your improvised leads or fill in riffs, no matter which color hand position you play. Try it! Be sure to add me to your favorites list!
