music from the 1980s tend to feature a lot of synthesizers and other electronic equipment. what does this suggest about the era

This suggests that the 1980s was a time when electronic music and technology played a significant role in the music industry. The use of synthesizers and other electronic equipment became prevalent during this era, resulting in a distinct sound that characterized much of the music from that time period.

The example of a sound without rhythm is a thunder clap. To understand why, let's first define what rhythm is. Rhythm refers to a pattern or regularity in the timing or sequence of sounds or events. It creates a sense of organization and repetition.

In the case of rain on a roof, while there may not be a strict musical rhythm, there is still a certain pattern or regularity to the sound. The droplets hit the surface of the roof at intervals, creating a consistent and repetitive pattern.

Similarly, horse hooves on a road also have a certain rhythm. When horses trot or gallop, their hooves strike the ground in a regular pattern, producing a rhythmic sound.

However, a thunder clap is an example of a sound without rhythm. Thunder is created by the rapid expansion and contraction of air due to a lightning bolt, producing a powerful shockwave. The sound of thunder is intense and unpredictable, lacking any discernible pattern or regularity. It often varies in volume, duration, and timing, making it an example of a sound without rhythm.

To identify sounds with or without rhythm, observe the patterns, repetitions, and regularities in the timing or sequence of the sounds. If there is a noticeable and consistent pattern, it indicates the presence of rhythm.
