There are soprano, concert, tenor and baritone ukuleles. Soprano being the smallest and having the brightest sound while baritone are the largest and warmer/lower sound. The soprano is the most popular and it’s sound is the one you will usually recognise the most. The baritone one has a sound that is almost a guitar. The concert and tenor sits in the middle. Mine is a Tenor uke. There is no wrong choice. Best would be to go to a store that sells both and give them a try and see which sound you prefer.

Here is the same song played on soprano and tenor ukuleles:
Soprano. Notice how you can’t see my face in this one. It was one of my first YouTube video and I was like you not comfortable showing myself on camera.

Tenor

This was so nice to listen, you gained a new Youtube subscriber haha. I like the sound of the tenor ukulele, it sounds more mellow somehow. And you gained more confidence in your voice in the second video.

I saw that there are wooden and plastic ukuleles. I saw bass and acustic ones too. Very interesting.
I will look at your channel and watch more.

When I will buy myself one be prepared to be bombarded with questions 🤣🤣🤣

You have a lot of patience to teach this, I think this can help many " I want to play an instrument" enthusiasts like me

Thank you for the nice words :-)
The mellow sound of the Tenor is why I chose it. Also for the ability to use a lower string for the top one (low G instead of high G). This allows me to play "Somewhere Over the Rainbow" with the bass line.

If you just want to explore, plastic or wooden does not matter. If you think you will get into it more seriously, you better choose solid wood or at least solid top ukulele as this will produce a much nicer sound. Bass ukulele are pretty cool indeed.

No pb, when you're ready, just ask me.
