Final answer:
Harmony in music is true, achieved by playing two or more tones together. It involves a combination of different frequencies and the unique timbres of instruments, contributing to the texture and emotional depth of a piece.
Step-by-step explanation:
Harmony in music is indeed accomplished by the simultaneous sounding of two or more different tones; therefore, the correct answer to the student's question is True. When various instruments like woodwinds and strings play together in an orchestra, they create a rich tapestry of sound where high frequency and lower frequency notes combine. While a single note, like middle C, can sound distinctively different on different instruments such as a trumpet or a clarinet due to different overtones and timbres, harmony focuses on the blend of multiple notes to create chords and a fuller sound.
Harmony is a fundamental concept in music that contributes to the texture and emotional quality of a piece. An illustrative example of harmony is how a piano tuner adjusts the strings to match a tuning fork's frequency, listening for the beats that occur when the frequencies are slightly off. Beats are an indication of two sound waves of slightly different frequencies interfering with each other, creating periodic increases and decreases in loudness. The concept of harmonics also plays a role here, where they must align with multiples of the fundamental frequency.
