### Understanding the Circle of Fourths

A circle of fourths is generated by starting at any note and stepping upward by intervals of a fourth (five half-steps). The circle of fourths is a fundamental concept in music theory that helps in understanding how different notes relate to each other.

### Key Questions:
1. **Frequency Increase Factor:**
   - By what factor is the frequency of a tone increased if it is raised by a fourth?

2. **Completion of the Circle:**
   - How many fourths are required to complete the entire circle of fourths?
   - How many octaves are covered in a complete circle of fourths?

#### Task:
- By what factor is a frequency increased if it is increased by a fourth?
  - (Round to three decimal places as needed.)

Complete the following tasks to enhance your understanding of the circle of fourths.

### Additional Information:
The circle of fourths is closely related to the circle of fifths and can be a useful tool in various aspects of music theory and practice, including chord progressions and key signatures.
