My voice is going unusually low today so I decided to sing a snippet of Charlie Puth's newest song "I Don't Think That I Like Her" an octave lower. (For comparison, I'm typically only able to go down to a C3. Anything below that is impossible for my voice to reach. Right now, I'm able to sing a G#2/Ab2, which is 4 half steps/2 whole steps below the C3.) Also, ignore the poor audio quality - I recorded this on my phone's camera app and converted it to an MP3 file afterward. Yes, that is my ceiling fan in the background.
