If you have a GCEA tuned ukulele you can easily and for free get a new and amazing tuning for you ukulele. Here's how you can tune your ukulele ABF#B. This is called D-tuning or Hawaiian tuning. The overall pitch of your instrument will be just a bit higher. This gives it a lighter and more playful and musical sound to my ear. If you don't like it, it will only take a minute to retune to GCEA. You don't have to change strings! If you have a low G,CEA ukulele, I think this will also work! I will know soon because I will be changing one or more of my Low G ukuleles to ABF#B.
My original songs suddenly sounds completely different when I play them on my ukulele. I didn't buy a new expensive ukulele. I didn't buy a new set of strings. I didn't even learn to play a cool, different way! All I did was attach a capo to the second fret. This changes the tuning from GCEA to A-D-F#-B.
‘Ironically this is now an alternate tuning these days, but years ago this is how ukes were normally tuned. Find any sheet music from the 1930's or before for uke and they often use D tuning which is A-D-F#-B. Now for those who know their music theory we have simply moved a step up in the tuning. A half step is one note and a whole step is two notes so a whole step from G is A, a whole step from C is D, from E to F# (remember there is no E#!), and the last A to B. If you have ever played in D tuning it has a perfect ukulele sound. It's surprising that this tuning is not used more often, however by using GCEA the new student has an easier time of learning. D-tuning however should not be overlooked and is perfect for songs that are in the Key of A because it's easier to play that dreaded E chord!' https://learnplayuke.com/different-types-of-uke-tunings/
