Arc Length to Chord Length Calculator


The ratio of arc length to chord length in a circle depends on the central angle subtended by the arc. To calculate it, you can use the formula:

Arc Length = Chord Length * (2 * π / 360) * θ

Where θ is the central angle in degrees. This formula relates the two lengths based on the angle formed by the arc.

    "II" in a chord notation typically represents a minor 7th chord. It is the second degree of the diatonic scale and includes the notes 1, 3, 5, and 7 with the 7th lowered by a half step.
  40. Are all chords in a circle the same length?
    No, not all chords in a circle are the same length. The length of a chord depends on its position within the circle and its relationship to the circle's center.

  42. Do all chords have the same length as the diameter?
    No, not all chords have the same length as the diameter. Only the chord that passes through the center of the circle (a diameter) has the same length as the diameter.
  43. What three chords are the most important in harmonization?
    The three most important chords in harmonization are typically the tonic chord (I), dominant chord (V), and subdominant chord (IV) in a major key. These chords form the basis of many musical progressions.
  44. Why is a dominant seventh chord so powerful?
    A dominant seventh chord is powerful in music because it creates tension and a strong desire to resolve to the tonic chord. This tension-resolution dynamic adds drama and excitement to music.
  45. What is the tonic of a chord?
    The tonic of a chord is the first degree or the root note of the chord. It is the note around which the chord is built and often serves as the point of rest or resolution in music.
