OK, if you haven't heard of Pentatonix by now, where have you been?!? But seriously, they are an amazing tool for the music room because of the variety of music they have performed. I love their version of The Sugar Plum Fairy, which I used in a lesson on arrangements recently, and their original music is great too. I have used them to discuss voice types (soprano/alto/tenor/bass), harmony, pitched vs. unpitched (with the beatboxing), and more. This video is a must-see though:
Walk Off the Earth is great for a lot of the same reasons as Pentatonix- I have used their videos to talk about voice types/parts, harmony, and more, but I love to use them as an example of making arrangements of songs because they often use classroom instruments in their videos, and they do so in such creative ways! They also tend to be "clean" so you can be pretty confident that you won't have to edit anything to show their videos to your kids. And let's not forget the perfect video for showing the different parts of the guitar (depending on age you may want to just show the instrumental)! But here's a great example of their arrangements with classroom instruments (their version of Cheerleader is pretty awesome too):

The Gregory Brothers are my secret ingredient for getting students to understand major and minor. They have tons of videos where they have taken popular songs and changed the tonality, but this "sampler" video will give you a good idea of what they can do:
There are plenty more wonderful resources out there on YouTube, but those are some of my favorites. What are your favorite YouTube channels for elementary music lessons? Share yours in the comments below!
