Graphing It Out: Data Visualization
Comparing Artists by the Numbers
Which artist has the most studio albums? How many more than J. Cole?
What percentage of the combined Grammy wins does Kendrick Lamar hold?
Create your own bar graph using this data in your notebook.
Fractions & Beats
The Math of Rhythm
Most hip-hop songs, including those by J. Cole, Kendrick Lamar, and Lil Wayne, use 4/4 time — meaning <b>4 quarter-note beats</b> per measure.
If a song has 32 bars and each bar has 4 beats, how many total beats are in the song?
If Lil Wayne raps 6 syllables per beat, how many syllables in 32 bars?
