#low notes

For example:

Songs credited to Voiceplay: Valhalla Calling, Oogie Boogie's Song, the Halo Theme

What do all of these videos have in common other than they're performed by the same Acapella group?

That's right: Layne Stein arranged them.

Now, that's not to say that Geoff never writes/arranges difficult songs for the group and for himself on his own YouTube channel (for instance, The Dragonborn Comes), but he tends to be more humble about his own abilities. Sure, he shows off and loves to push himself to hit lower notes, but he knows the limit of his vocal abilities and likes to write parts specifically made for the other members of the group.

Layne, on the other hand, takes his turn at arranging for the month, and goes:

Layne: Geoff, how low can you sing?

Geoff: *gives him a reasonable answer*

Layne: okay yeah, sounds good.

*time passes between the conversation and the song being arranged and ready to record*

Geoff: *listens to his part for the song* Layne what is this. I told you I can sing a C1. But here you have me singing an A flat -3!

Me: *sings low note perfectly*

Everyone: Wow, you're a good singer.

Teacher: Now try singing (insert song name which is sung in a high-ass key)

Me: ...

Me: *sings it in a lower key*

Teacher: Nonono. Sing it in the original key.

Me: ...

Me: *screeches like a dying cat*

Everyone:
