  2. Ptolemy's table of chords - Wikipedia

    en.wikipedia.org/wiki/Ptolemy's_table_of_chords

    For tiny arcs, the chord is to the arc angle in degrees as π is to 3, or more precisely, the ratio can be made as close as desired to ⁠ π / 3 ⁠ ≈ 1.047 197 55 by making θ small enough. Thus, for the arc of ⁠ 1 / 2 ⁠ °, the chord length is slightly more than the arc angle in degrees. As the arc increases, the ratio of the chord to ...

  3. PEG ratio - Wikipedia

    en.wikipedia.org/wiki/PEG_ratio

    In general, the P/E ratio is higher for a company with a higher growth rate. Thus, using just the P/E ratio would make high-growth companies appear overvalued relative to others. It is assumed that by dividing the P/E ratio by the earnings growth rate, the resulting ratio is better for comparing companies with different growth rates. [1]

  4. Guitar chord - Wikipedia

    en.wikipedia.org/wiki/Guitar_chord

    Open tunings allow one-finger chords to be played with greater consonance than do other tunings, which use equal temperament, at the cost of increasing the dissonance in other chords. The playing of (3 to 5 string) guitar chords is simplified by the class of alternative tunings called regular tunings , in which the musical intervals are the ...

  5. Regular tuning - Wikipedia

    en.wikipedia.org/wiki/Regular_tuning

    The shifting of chords is especially simple for the regular tunings that repeat their open strings, in which case chords can be moved vertically: Chords can be moved three strings up (or down) in major-thirds tuning, [3] and chords can be moved two strings up (or down) in augmented-fourths tuning. Regular tunings thus appeal to new guitarists ...

  9. Chord-scale system - Wikipedia

    en.wikipedia.org/wiki/Chord-scale_system

    In contrast, in the chord-scale system, a different scale is used for each chord in the progression (for example mixolydian scales on A, E, and D for chords A 7, E 7, and D 7, respectively). [5] Improvisation approaches may be mixed, such as using "the blues approach" for a section of a progression and using the chord-scale system for the rest. [6]
