I’m sorry to report that women artists didn’t gain much ground this year. And even though male-female duets saw a healthy bump, not even one strictly female duet showed up to the party, while a full third of our 2018 “Top 5-ers” had at least two dudes in the room! I don’t know, maybe blame it on the surplus of Drakes lying around?
A great example of this technique comes from P!nk. At 2:03 in “Walk Me Home,” she sings the chorus an octave below, accompanied by nothing but an acoustic guitar, which makes the final chorus that returns later all the more impressive and memorable.
