Tone
[responsivevoice_button]
I coupled Tone with Width since I had already decided to place Pitch with Height however, once again, there is no reason to look at tone as something that is measured as width. The reason I am using length, width and height is to show that sound, like objects has different dimensions that make up it’s form. If you turn a box on it’s side for example, the height is now used to measure a different side, regardless of it’s actual measurement. It is however, a different measurement that helps us understand the dimensions of an object.
While Pitch describes the frequency at which the sound oscillates/vibrates, Tone refers to the quality of the sound itself. Therefore what pitch is to height, tone is to width in that it measures a different dimension or quality of a sound. Once we have established a pitch to focus on, we’ll want to describe what that pitch sounds like in terms of tone. Unfortunately Tone is also measured in frequencies therefore it can cause confusion with frequencies of pitch. There is actually a direct relationship however equalization refers to the bass, middle, and treble of a sound. Anyone who has listened to music on a medium such as radio, television, or even a phone has noticed that they can modify the bass, middle, and treble settings to their preferences. Modifying these settings does not change the actual song itself however you are choosing to amplify or reduce the volume of bass, middle, or treble frequencies in a way that is more pleasing to your ears. Equalization can be applied to the sound that is being created or to the equipment used to listen to the sound/musictherefore it can be both a part of the original sound as much as a preference setting while listening back to the sound. Pitch however is predetermined by the musician therefore the act of modifying the pitch would actually be a modification to the song altogether. More on this later.
When a sound is created, it is actually made up of multiple frequencies that are occurring at the same time. There is however one fundamental frequency, which is the main and most obvious sound you hear, giving the perception that there is only one frequency however there are actually multiple other frequencies, called enharmonic tones, that are taking place at different volumes and at the same time, which give it the unique sound you are experiencing. The enharmonic tones are related to the fundamental frequency, usually a combination of doubling the frequency but not limited to doubling, therefore the elimination of any of the secondary frequencies will not change the pitch of the sound since the fundamental frequency is still present and even implied by all the other frequencies. Removing the fundamental frequency will automatically also remove the secondary frequencies to a certain degree since they only exist because of the fundamental frequency (and how our ears interpret it) therefore the pitch would still be the same except much quieter since ‘removing’ a frequency is simply lowering of the volume of that frequency. Changing the frequency by making it faster or slower however will affect the pitch as you are speeding up/slowing down the fundamental frequency (which will also automatically move all other secondary frequencies along with it) however the adding or removing of a frequency (ie. Using an equalizer), is simply the act of raising or lowering the volumes of frequencies.
A high pitch can therefore still have lots of bass frequencies present and a low note can still have lots of treble since tone frequencies are more related to the quality of the sound itself and not pitch.
Quick side note about Bass: When we refer to ‘bass’ we are referring to sound frequencies rather than a bass guitar instrument. The reason a bass guitar is called bass is because it is usually used to play lower sounding notes (lower pitches) as accompaniment to a guitar for example, however even a bass guitar can have specific bass, middle, and treble frequencies in it’s tone or sound spectrum. A bass guitar is therefore not only bass frequencies. Perhaps it could have been named differently to avoid confusion … just as a French Horn is named differently from a Trumpet. This is why you will often see the term ‘bass guitar’ when referring to the instrument instead of tone (which is simply ‘bass’).
As stated, a note has multiple frequencies in play at any given moment regardless of the pitch being played. Bass frequencies are therefore lower sounding frequencies within the audio/sound spectrum (300 Hz and below) while Middle frequencies are slightly higher (around 600 Hz) , and Treble frequencies are much higher sounding (1 KHz and up). The names ‘bass, middle, and treble’ are simply names given to a range of frequencies so that we don’t need to memorize actual frequency numbers however there are specific times, especially for sound engineers (and perhaps ear specialists) where the actual frequency number is necessary.
Since Tone and Pitch are directly related, a person who has trouble hearing treble frequencies will also have trouble hearing higher pitches clearly. Modifying the volume levels of various frequencies can help a person hear something better as you can target specific frequencies that may be troublesome. Tone and Pitch can be compared to a man and woman where: A man usually has a lower pitched voice and a woman has a higher pitched voice however if they are both speaking through a microphone, you can still adjust their individual tone by adding more bass, middle, or treble to their sound yet they would still each sound like a man or a woman. Tone will not change pitch however it can help make sounds brighter or darker sounding. Adding more treble would make either voice a little clearer as higher frequencies tend to be easier to hear, while adding more bass, or middle, would help their voices sound fuller or thicker, and even muddier or ‘boomy’ if too much is added or if too much treble is removed.
