16 bars of a song is a musical phrase equivalent to 64 beats in common 4/4 time (16 bars x 4 beats/bar), often lasting 30-45 seconds and typically forming a verse or a significant section like a verse-chorus combination, appearing as 16 lines of lyrics or 16 measures on sheet music, depending on tempo and style. Visually on paper, it's 16 sets of notes separated by bar lines, while aurally, it's a consistent rhythmic segment that feels complete, like a standard rap verse or a theatrical audition piece.
Measure Time Not Bars

So, 16 lines down the paper will equal to 16 bars. And to double check, what you usually do is you find the section of the song, of an instrumental, that is the same amount of time as a regular 16 bar verse.
The 80/20 rule (Pareto Principle) in songwriting means 80% of a song's impact, memorability, or success comes from just 20% of its elements, like the core hook, chorus, or lyrical phrase, with the rest being polish. It encourages songwriters to identify and focus on these high-impact areas (e.g., catchy melodies, strong core lyrics) to maximize results, while also applying the principle to their process by focusing on the 20% of activities that yield 80% of their progress, such as identifying the few core skills or marketing efforts that truly work.

It's a principle rooted in human psychology, making music more memorable and satisfying by balancing repetition with novelty, applying to melodies, rhythms, and even the number of elements in a musical passage.
