READING MUSIC 3 - Quiz Answers The level ( high, low) of its sound. The distance (pitch difference) between two notes. Two notes sounded simultaneously. Two notes sounded one after the other. Interval between two notes more than one octave apart. A unison. An octave. The intervals are : C - B = 7th B - C = 2nd D - G = 4th G - D = 5th F - A = 3rd A - F = 6th The interval B - C is the 'upside down version' (inversion) of C - B Likewise the interval G - D is the inversion of D - G,and the interval A - F is the inversion of F - A. The number of any interval and its inversion always add up to 9.7 + 2 = 94 + 5 = 93 + 6 = 9 The compound intervals are : C - E = 10th C - G = 12nd E - C = 13th B - E = 11th F - E = 14rd D - E = 9th The number of a compound interval is always 7 more than its related simple interval with the same letter name : a 2nd becomes a 9th, a 3rd becomes a 10th, a 4th becomes an 11th, and so on.
