Composers sometimes find it hard to use tempo, or the speed of music, to build tension and then let it go. Here are some reasons why:

• Complicated Tempo Changes: When the speed of the music changes quickly, it can confuse people who are listening.
• Finding the Right Balance: It's tough to choose the perfect time to speed up or slow down the music.

Solutions:

• Slow Changes: Try making small changes in tempo. This keeps the listeners interested.
• Clear Instructions: Use clear markings to show performers how to change the tempo.

These tips can help composers create the music effects they want without too much trouble.
