I was able to apply ukulele to whatever I'm trying to write. It's become part of songwriting for me, the knowledge I gained from hearing the melodies come out, and then applying that to guitar or vocals.
I learned so much about music by playing this little, miniature songwriting machine [ukulele], especially about melody. The motto is less strings more melody.
I had a $1.50 from playing the ukulele after owning it seven minutes. I thought, "Hmmm, this has some possibilities."
Things like guitars and ukuleles, you should never part with it, because there will probably be good, healthy times spent, just playing and writing.
