how can i play guitar and harmonize with a ukulele??? all help and input apprecitated...
Unless the ukulele is a dropped D tuned baritone, a guitar has three things slightly different than an ukulele: use those to provide contrast. (1) No ukulele has the bass range of a guitar. Even a dropped D bari has nothing as low as the fifth and sixth strings that a guitar does. Anything you do on those strings of a guitar will be different than what any uke can play. (2) Ecept for baritone ukes, an uke is tuned like the first four strings of a guitar with a capo across the fifth fret. Anything you play below the fifth fret is below the range of all soprano, concert, and tenor ukuleles. If you stay in those 1st position areas of the guitar fretboard, you add dimensions that the uke cannot go. (3) Unless the uke has dropped G (D with a baritone) tuning, ukuleles have a reentrant tuning, adding a uke charm that guitar does not have. This provides a contrast similar to a 5-string banjo playing with a guitar. Use that contrast for beauty.
Beyond that, anything you can play as a duet on two guitars or two ukuleles is good. Unison melody lines, harmony melody lines, counterpoint, or even the simplest of one playing chords while the other plays a melody is great. Have one strum a straight 4/4 beat while the other strums a complex rhythmic pattern. Strum the guitar in 1st position while the uke strums higher up the neck for contrast.
Use that fourth tuning difference for contrast and the harmony will be there automatically.
