<span>This style of chanting is called organum. Organum is a form of music from medieval times that is based on an existing melody. It includes an added voice that helps enhance the harmony of the music. It is often seen in Gregorian chanting and is one of the earliest types of music.</span>
Neolithic period in what we see in technology and settled life. It began between 10,200 BC. Neolithic is also considered as the last part of the stone age.
Decibels are the units that are used to measure amplitude of sound waves.
<h2>Further Explanation
</h2><h3>Waves </h3>
- Waves are a transmission of a disturbance. They involve transmission of energy form one point called the source to another.
- Waves can be classified as either transverse waves or longitudinal waves
<h3>Transverse waves </h3>
- A transverse wave is a wave in which the vibration of particles if perpendicular to the direction of wave motion.
- Transverse waves contains regions of maximum displacement called crests and regions of minimum displacement called troughs.
- Examples of transverse waves are x-rays, radio waves, etc.
<h3>Longitudinal waves </h3>
- Longitudinal waves are types of waves in which the vibration of particles is parallel to the direction of wave motion.
- Longitudinal waves contains regions of minimal displacement of particles called compressions and those of maximum displacement of particles called rarefactions.
- Examples of sound waves include sound waves.
<h3>Sound waves </h3>
- Sound waves are examples of longitudinal waves.
- In addition sound waves are mechanical wave as they require a material medium for transmission.
<h3>Amplitude in sound waves
</h3>
- Amplitude in sound waves refers to the extent to which particles of air are displaced normally experienced as the loudness of sound.
- The loudness of a sound wave corresponds to the amplitude of the wave and is measured in decibels.
<h3>Frequency of sound wave
</h3>
- Frequency refers to the number of complete oscillations by particles in a wave in a second.
- Frequency of a sound waves determines the pitch of the sound. Frequency is measure in Hertz.

I'm not that quite sure but the Surrealism was a movement in Europe with the onset of the World War II.
