I really want to learn to play a musical instrument. Ever since my "keyboard" lessons as a kid 3 decades ago - I have been put off.
I learned songs on keyboard by "rote" i.e., the instructor scribbled the notes for me to play and I had to memorize them. Over time I hated my music class. However, a friend recently suggested a stringed instrument such as guitar/ukulele might be something worth looking into as an instrument that does not require mastery of musical theory or reading music to be able to play songs.
I have absolutely abysmal/zero understand of musical theory. E.g.: I don't even know what a "chord" means and how a song is composed of chords (I know the definition of a chord, but don't understand it musically.)
My primary aim is to learn to play songs by ear, strum for fun with friends over or just meditate by playing for myself in a closed room, but being "good enough" at it to keep it interesting. I can set aside up to 3-4 hours a week for musical endeavors so something that's learnable over time within such time frames might fit my needs.
Between Guitar and Ukulele, what are the differences and other considerations that I might want to take into consideration when choosing an instrument to learn to play?
