This cheat sheet explains how note and rest durations fit together like a tree, from longer sounds to shorter sounds. Students need this reference to read rhythms, count beats, and understand how notes divide evenly in common time. It helps connect the look of a symbol with how long it lasts in music.
Key Facts
- A whole note equals 4 beats in 4/4 time, and a whole rest also equals 4 beats of silence.
- A half note equals 2 beats, so 2 half notes = 1 whole note.
- A quarter note equals 1 beat, so 4 quarter notes = 1 whole note.
- An eighth note equals 1/2 beat, so 2 eighth notes = 1 quarter note.
- A sixteenth note equals 1/4 beat, so 4 sixteenth notes = 1 quarter note.
- A rest has the same duration value as the note with the matching name, but it means silence instead of sound.
- A dot adds half of the note's original value, so a dotted half note equals 3 beats.
- In 4/4 time, one measure must contain note and rest values that add up to 4 beats.
Vocabulary
- Duration
- Duration is how long a note or rest lasts in music.
- Beat
- A beat is the steady pulse that musicians count while playing or singing.
- Note
- A note is a symbol that tells a musician to make a sound for a certain length of time.
- Rest
- A rest is a symbol that tells a musician to be silent for a certain length of time.
- Duration Tree
- A duration tree shows how longer note values divide into equal shorter note values.
- Dotted Note
- A dotted note lasts for its normal value plus half of that value.
Common Mistakes to Avoid
- Counting a whole note as 1 beat is wrong because in 4/4 time a whole note lasts for 4 beats.
- Forgetting that rests have beat values is wrong because silence still takes up time in a measure.
- Mixing up eighth notes and sixteenth notes is wrong because an eighth note is 1/2 beat, while a sixteenth note is 1/4 beat.
- Adding a dot as 1 extra beat every time is wrong because a dot adds half of the note's original value.
- Writing too many beats in a 4/4 measure is wrong because each measure must add up to exactly 4 beats.
