There are certain songs in Hawaiian music that work very well for and are embraced by slack key guitarists. Maori Brown Eyes is one of those. It’s an easy piece, but with much room to improvise and run licks. It’s also great on the ‘ukulele, as shown by Troy Fernandez on his Hawaiian Style ‘Ukulele album.
Here’s my tab of the melody in C. Very basic, but a great frame for building a solo arrangement or practicing precise timing with a metronome.
