Question 15

Three or more pitches sounded simultaneously are known as a chord.

A chord is defined as a combination of three or more musical pitches played or sung at the same time, creating harmony.

A) a melody

A melody refers to a sequence of single notes that are musically satisfying; it is not characterized by multiple pitches played simultaneously. Therefore, this option does not fit the definition given in the question.

B) frequency

Frequency refers to the number of occurrences of a repeating event per unit of time, and in music, it relates to the pitch of a sound. However, it does not describe a simultaneous combination of pitches, making this option incorrect.

C) a motive

A motive is a short musical idea or phrase that can be developed throughout a piece of music. It does not encompass multiple pitches played at once; thus, this option does not align with the question's context.

D) a cadence

A cadence is a melodic or harmonic configuration that creates a sense of resolution or pause in music. While important in musical structure, it does not represent a simultaneous sound of three or more pitches, rendering this option incorrect.

E) a chord

A chord is accurately defined as the simultaneous sounding of three or more pitches, making this the correct answer to the question posed.

Conclusion

The correct answer, a chord, effectively captures the essence of three or more pitches being sounded together, which is fundamental in music theory. All other options fail to describe this concept accurately, focusing instead on distinct musical elements that do not involve simultaneous sound. Thus, the definition of a chord is essential in understanding harmonic structures in music.
