Now that you have learned these 4 essential chords you have opened up a TON of songs. Again, I will supply a few but you are welcome to search out any other song. If you come across a favorite song that has a chord we haven't learned then learn it on your own!! You can read a chord chart. I have given you plenty of tools to do this on your own. Don't be afraid. Go do it!
Also... with some play along videos the singing may sound strange because they have been altered to accommodate the key of the ukulele.
www.ukeability.org is a great resource to find other songs!
I LOVE THIS SHOW. This song has a challenging verse as the chords change quickly, but you can totally do it.
This song has a few "extra" chords. They are written smaller which means they're optional. You can just keep playing the chord before it. If you're needing a challenge then I encourage you to pause the video, check out those chords, and give it a try. Hint: for Bb (which stands for B-flat) you use your first finger to press the 1st and 2nd string at the same time.
The tricky part to this song is timing. The chords change quickly but also not on normal expeted beats. Its fun either way.
Here's a full blown tutorial. There may be some review or maybe he explains it in a way that solidifies something for you.
