  2. Key signature - Wikipedia

    en.wikipedia.org/wiki/Key_signature

    [9] [10] The key note or tonic of a piece in a major key is a semitone above the last sharp in the signature. [11] For example, the key of D major has a key signature of F ♯ and C ♯, and the tonic (D) is a semitone above C ♯. Each scale starting on the fifth scale degree of the previous scale has one new sharp, added in the order shown. [10]

    en.wikipedia.org/wiki/Closely_related_key

    In the key of C major, these would be: D minor, E minor, F major, G major, A minor, and C minor. Despite being three sharps or flats away from the original key in the circle of fifths, parallel keys are also considered as closely related keys as the tonal center is the same, and this makes this key have an affinity with the original key.

    en.wikipedia.org/wiki/Piano_key_frequencies

    This is a list of the fundamental frequencies in hertz (cycles per second) of the keys of a modern 88-key standard or 108-key extended piano in twelve-tone equal temperament, with the 49th key, the fifth A (called A 4), tuned to 440 Hz (referred to as A440). [1] [2] Every octave is made of twelve steps called semitones.

    Mozart and Haydn wrote most of their masses in C major. [3] Gounod (in a review of Sibelius' Third Symphony) said that "only God composes in C major". Six of his own masses are written in C. [4] Of Franz Schubert's two symphonies in the key, the first is nicknamed the "Little C major" and the second the "Great C major".

    In popular music and rock music, "borrowing" of chords from the parallel minor of a major key is commonly done. As such, in these genres, in the key of E major, chords such as D major (or ♭ VII), G major (♭ III) and C major (♭ VI) are commonly used. These chords are all borrowed from the key of E minor.

  8. Radian - Wikipedia

    en.wikipedia.org/wiki/Radian

    One radian is defined as the angle at the center of a circle in a plane that subtends an arc whose length equals the radius of the circle. [6] More generally, the magnitude in radians of a subtended angle is equal to the ratio of the arc length to the radius of the circle; that is, =, where θ is the magnitude in radians of the subtended angle, s is arc length, and r is radius.

    In this right triangle, denoting the measure of angle BAC as A: sin A = ⁠ a / c ⁠; cos A = ⁠ b / c ⁠; tan A = ⁠ a / b ⁠. Plot of the six trigonometric functions, the unit circle, and a line for the angle θ = 0.7 radians. The points labeled 1, Sec(θ), Csc(θ) represent the length of the line segment from the origin to that point.
