問題

  1. math on the spot frets are small metal bars positioned across the neck of a guitar so that the guitar can produce the notes of a specific scale. to find the distance a fret should be placed from the bridge, multiply the length of the string by $2^{-\frac{n}{12}}$, where $n$ is the number of half steps higher than the strings root note. where should a fret be placed to produce an a flat note on the e string (four half steps higher)? 64 cm

解法ステップ

  1. Understand the question
    1. math on the spot frets are small metal bars positioned across the neck of a guitar so that the guitar can produce the notes of a specific scale. to find the distance a fret should be placed from the bridge, multiply the length of the string by $2^{-\frac{n}{12}}$, where $n$ is the number of half steps higher than the strings root note. where should a fret be placed to produce an a flat note on the e string (four half steps higher)? 64 cm
  2. Explanation

    Step1: Identify given values

    String length $L = 64$ cm, $n = 4$

    Step2: Apply the given formula

    The distance formula is $\text{Distance} = L \times 2^{-\frac{n}{12}}$
    Substitute values: $\text{Distance} = 64 \times 2^{-\frac{4}{12}} = 64 \times 2^{-\frac{1}{3}}$

    Step3: Calculate the value

    First, $2^{\frac{1}{3}} \approx 1.26$, so $2^{-\frac{1}{3}} \approx \frac{1}{1.26} \approx 0.7937$
    Then $\text{Distance} \approx 64 \times 0.7937 \approx 50.8$ cm

  3. Final answer

    The fret should be placed approximately 50.8 cm from the bridge.

Explanation

Step1: Identify given values

String length $L = 64$ cm, $n = 4$

Step2: Apply the given formula

The distance formula is $\text{Distance} = L \times 2^{-\frac{n}{12}}$
Substitute values: $\text{Distance} = 64 \times 2^{-\frac{4}{12}} = 64 \times 2^{-\frac{1}{3}}$

Step3: Calculate the value

First, $2^{\frac{1}{3}} \approx 1.26$, so $2^{-\frac{1}{3}} \approx \frac{1}{1.26} \approx 0.7937$
Then $\text{Distance} \approx 64 \times 0.7937 \approx 50.8$ cm

Answer

The fret should be placed approximately 50.8 cm from the bridge.
