Question

Use the following notation image to answer the question.
How many quarter notes are in the notation excerpt?

Four measures of rhythm written in four four time as follows: Measure 1: Two half notes; Measure 2: Four eighth notes, quarter note, quarter rest; Measure 3: Two quarter notes, two eighth notes, quarter note; Measure 4: Whole note.

Answer 1

To determine the total number of quarter notes in the notation excerpt, let's analyze each measure:

1. **Measure 1:** Two half notes. Each half note is equal to two quarter notes. Therefore, there are:
- \( 2 \text{ half notes} \times 2 \text{ quarter notes/half note} = 4 \text{ quarter notes} \)

2. **Measure 2:** Four eighth notes, one quarter note, and one quarter rest. The four eighth notes are equal to two quarter notes:
- \( 4 \text{ eighth notes} \div 2 = 2 \text{ quarter notes} \)
- Plus 1 quarter note.
- Total for Measure 2: \( 2 + 1 = 3 \text{ quarter notes} \)

3. **Measure 3:** Two quarter notes, two eighth notes, and one quarter note. The two eighth notes equal one quarter note:
- \( 2 \text{ quarter notes} + 1 \text{ quarter note from eighth notes} + 1 \text{ additional quarter note} = 4 \text{ quarter notes} \)

4. **Measure 4:** One whole note. One whole note is equal to four quarter notes:
- \( 1 \text{ whole note} = 4 \text{ quarter notes} \)

Now, let's sum the quarter notes from each measure:

- Measure 1: 4 quarter notes
- Measure 2: 3 quarter notes
- Measure 3: 4 quarter notes
- Measure 4: 4 quarter notes

Total quarter notes:
\[ 4 + 3 + 4 + 4 = 15 \]

So, there are **15 quarter notes** in the notation excerpt.
