1. Key Words Exercise (novice)
Another possibility is for students to receive a visual cue via an annotation which remains visible on the video until the word is sung. See the video below for several examples of annotations (viewed by clicking annotations) created thanks to the very same platform that hosts this multimedia workshop, Scalar.
A chorus provides a predictable opportunity for students to identify a word even if they missed it the first time. This exercise can also take the form of a game, with groups of students gaining or losing points according to their ability to identify or misidentify key words from the lyrics.
