Do you want to learn an instrument, but you want one that is relatively uncomplicated?
Learn to play the ukulele.
The ukulele has the advantage of being a small instrument, great for youngsters and for seniors. You do have the option of picking from different types of ukuleles, which come in different sizes, but most are small compared to other heavier instruments like the guitar. There is the soprano, the concert, the tenor, and the baritone ukulele.
There are even other types of ukuleles that have odd shapes like a pineapple, and are appropriately called "pineapple" ukuleles.
The ukulele is a very simple four-string instrument. It is usually tuned to G-C-E-A, which is the one most people use to learn to play the ukulele. However, some people tune the strings to A-D-F#-B.
Learn How to Tune a Ukulele
You do not need much musical experience when tuning a ukulele. Here is a very good website you can use to get your uke tuned just right.
You will also need to be able to read sheet music for the ukulele, and learn how to place your fingers to generate the right chords. This is not as difficult as it sounds, but if you want to have someone show you, you can still opt to get ukulele lessons from someone.
Otherwise, ukulele players use what is known as a ukulele chord chart to figure out where to place their fingers. This is a very visual aide that allows the new player to see what strings are to be used to create the chord, and where the fingers should go on the board.
Practice Your Strumming!
It's not hard to find some basic, beginner's music that you can attempt once you've tuned your ukulele. If you don't know how to tune one, you can probably get a music shop to do it for you. Then, take it home and try following the chord chart to see if you can play some songs.
It may take a bit of instruction and practice, but many people learn to play the ukulele without formal instruction. To master it, however, will take much practice, as the pieces get more complicated. Once you understand where your fingers go to create a chord, just strum all the strings and listen to hear if the music sounds good. That's really all there is to it!
