Are you lowering the key of all these songs? I was following a female Ukulele player here on RU-vid and struggled so match to sing along to what I strummed. So much better with your videos! But I don't know much (yet) about keys
I did lower the key to match my vocal range, and to play this song with basic chords that make it easy for beginners. But you can always apply a capo and still use the same chord shapes to perform this song in any key you desire
Thanks for uploading. If you have a minute, I recorded a cover of Ed Sheeran. As a fellow music fan, I'd love if you'd check it out. It's on my page. Hope you enjoy!
