With most music instruments, students make use of markings on their instruments to identify the positioning of certain frets. With guitars and ukuleles these are typically in the form of points which can be found along the fretboard. Most Cuatros do not have these markings, so we simply have to improvise. Some persons get familiar with this by a change in the fretboard such as the coloring of the wood or a mark as a result of constant playing. Others choose an easy method (recommendable) which is they simply put a small sticker to mark a point of reference. The point of reference is up to you, one tip would be to make use of the 8th fret as a reference point simply because counting tends to get difficult after the 5th fret, but again this is up to you.
