Amplitude –
Amplitude is the size of the vibration, and this determines how loud the sound is. We have already seen that larger vibrations make a louder sound.
Frequency and Pitch
Frequency and pitch describe the same thing, but from different viewpoints. While frequency measures the cycle rate of the physical waveform, pitch is how high or low it sounds when you hear it.
This is directly related to frequency: the higher the frequency of a waveform, the higher the pitch of the sound you hear.
Think of the sound of a car or motorcycle engine accelerating. As the engines turns faster (at a higher frequency) the engine makes a higher-pitched sound.
Human ears can only hear sounds within a certain range of frequencies. As people grow older, their hearing range reduces. A young person can usually hear sounds in the range of 20 Hz to 20,000 Hz.
Chords
In music, a chord is three or more notes that combine harmoniously. You can play chords on a piano or guitar, but not on an instrument that plays one note at a time, like a trumpet.
Beat
Beat is defined as a rhythmic movement, or is the speed at which a piece of musicis played. An example of beat is the beating of a heart. An example of beat is the rhythmic noise played on a drum. An example of a beat is the tempo at which a conductor leads an orchestra to play.
Tempo
If no one is dancing at your party, you probably want to put on some music with a faster tempo — meaning a faster speed.
Panning
Panning is the distribution of a sound signal (either monaural or stereophonic pairs) into a new stereo or multi-channel sound field determined by a pan control setting. A typical physical recording console has a pan control for each incoming source channel.
Attack, Sustain, Release
Attack is the timing it takes to the note to hit the higher intensity ;
Sustain is the timing the note is held to the highest intensity ;
Release is the timing it takes to get back to the 0 value;
Harmonics
Harmonics in music are notes which are produced in a special way. They are notes which are produced as part of the “harmonic series”.
Timbre
In music, timbre is the perceived sound quality of a musical note, sound or tone. Timbre distinguishes different types of sound production, such as choir voices and musical instruments, such as string instruments, wind instruments, and percussion instruments.
