9. Half Notes & Whole Notes
Theory Lesson: Let It Ring
Music needs to breathe! If you just played fast notes on every single beat, it would sound exhausting. Sometimes, we want a note to ring out and fill the space.
The Whole Note
A whole note looks like an empty, hollow oval with no stem. In 4/4 time, a whole note takes up the entire measure. It gets exactly four beats. When you play a whole note, you press the key on Beat 1, and you hold that key down through Beats 2, 3, and 4 before letting go.

The Half Note
A half note looks a lot like a whole note (an empty oval), but it has a straight stem attached to it. Just like the name says, it is worth exactly half of a whole note. In 4/4 time, a half note gets two beats.
This means you can fit two half notes into a single measure. You would play the first one on Beat 1 (holding it through Beat 2), and play the second one on Beat 3 (holding it through Beat 4).

Practice Session: Holding Notes
The Goal: Train yourself to hold keys down for their exact mathematical length without cutting them short.
The Execution: Open JazzPianoLab and run through these Rhythm exercises:
- 9.1 Whole Notes: The Four-Beat Hold: Practice pressing a key and holding it down patiently for a full four clicks before moving on.
- 9.2 Half Notes: The Two-Beat Step: Walk up and down the keyboard holding each note for exactly two clicks.
- 9.3 Mixed Rhythms: Single Key: Switch between whole, half, and quarter notes on the exact same key to test your internal rhythm math.
- 9.4 Hand Independence: Hold and Play: A great brain workout! Your right hand holds a long whole note while your left hand plays four quarter notes beneath it. Then switch hands.
