Musicians struggle to understand and apply complex tempo markings in different time signatures

Musicians encounter confusing tempo notation systems where the same BPM value means different things depending on the time signature (e.g., quarter note = 144 in cut time vs common time). This creates performance errors, miscommunication between composers and performers, and wasted rehearsal time trying to figure out the correct speed. Existing music theory resources don't clearly explain the relationship between note values and tempo across different time signatures.
