As far as contemporary Hawaiian music goes, Keali’i Reichel is one of my favorite artists. Everything he does is great, live or in the studio.
Hanohano Ka Lei Pīkake is a simple tune so it’s natural to teach it to beginning students. You don’t find an easy and great-sounding song everyday. The problem is singing it like Keali’i!
It is not in the key of the recording (Ab) so you can’t play along. But if you want to learn it, spin the song on repeat for a couple days until you know how it’s supposed to sound really well. Then pick up your ‘ukulele and start strumming the chords and humming. Unless you’re competent in the Hawaiian language, definitely don’t try singing the words right away! They are relatively difficult and will taking some studying on their own. So learn the timing and chord changes while humming and then (and only then) try to add in the words.
