Piano and Forte: Dynamics

Core Idea

Dynamics are the louds and softs of music. Musicians use Italian terms: piano (p) means soft, forte (f) means loud, mezzo-piano (mp) means medium-soft, and mezzo-forte (mf) means medium-loud. These markings appear in written music to tell performers how loud or soft to play.

How It's Best Learned

Practice playing or singing a phrase at different dynamic levels: piano, mezzo-forte, forte. Write the dynamic symbols on cards and hold them up while the class plays, changing volume in real time. Listen to recordings and identify where the dynamics change.

Common Misconceptions

• Confusing piano the dynamic marking with piano the instrument; the instrument was named "pianoforte" because it could play both soft and loud.
• Thinking forte means as loud as possible; forte is loud but controlled, with fortissimo (ff) being even louder.
• Believing dynamics stay the same throughout a piece; most music changes dynamics frequently for expression.

Explainer

Dynamics are the louds and softs of music. They are one of the most important ways musicians make music expressive and interesting. Imagine if someone told you a whole story in the exact same volume of voice the entire time. It would get boring quickly. Music works the same way. Changing from loud to soft and back again keeps listeners engaged.

Musicians use Italian words to describe dynamics because many musical traditions started in Italy. The two most basic dynamic markings are piano, which means soft, and forte, which means loud. These are written in sheet music as the letters p and f. When you see a small p under the notes, you play softly. When you see an f, you play loudly.

There are also levels in between. Mezzo-piano (mp) means medium-soft, and mezzo-forte (mf) means medium-loud. The word "mezzo" means medium or half. So dynamics give musicians at least four levels of volume to work with: soft, medium-soft, medium-loud, and loud. There are even more extreme levels like pianissimo (pp) for very soft and fortissimo (ff) for very loud.

Here is a fun fact: the instrument we call a piano got its name from these dynamic markings. Its full name is pianoforte, meaning "soft-loud," because when it was invented, it was special that one instrument could play both softly and loudly. Older keyboard instruments like the harpsichord could not change their volume much at all. So next time someone mentions piano, think about whether they mean the instrument or the dynamic marking.
