[Physics Class Notes] on Timbre Pdf for Exam

During a musical performance, we all love to judge the voice of singers. At this moment, we get more attracted to a magical musical voice. A person maintaining a good pitch and intensity is heard the most. The same scenario can be explained in Physics.

So, a voice timbre is the quality of the musical sound or a human voice (vocal timbre). So, if there are two or more sounds with the same frequency, the melodious one is a timbre. 

Define Timbre

In the musical world, timbre is known as tone colour or tone quality under the field of psychoacoustics. It is also recognized as the colour or the quality, and tone of a sound that makes it unique.

We define timbre as the heard sound quality of a musical note, sound, or tone. Timbre can distinguish several sound productions, such as choir voices, musical instruments, string instruments, wind instruments, and percussion instruments. 

Timbre also enables listeners to distinguish different instruments in the same category (same pitch and frequency). 

What is Timbre?

Let’s suppose that you and your friend compete in a music competition. You like to play Casio and your friend loves to play the guitar. However, you are good at making various beautiful tones that mean the tune quality is higher as compared to your friend. While your friend has a melodious voice than yours.

In the first scenario, your musical tones have good quality, while your friend has a good tone quality.

So, timbre considers a melodious sound coming from your instrument. Here, the good sound coming out of your musical notes is timbre.

Timbre also considers the melodious human voice. This category of timbre is vocal timbre or a voice timbre.

If you are a; singer, you know that a breathy sound is created by putting a lot of air behind each note as you sing.

Some examples of timbre are the ways used to express the sound, so terms like Flat, Light, Smooth, Smoky, Breathy, and Rough are what you use to differentiate one sound from another. How you recognize various sounds or voices you hear is attributed to the timbre (voice timbre).

So, from the above example, we understood that there are different types of timbre. Let’s understand these one-by-one:

Different Types of Timbre

The different types of timbre are as follows:

• Hamonic – A concert where all the musicians are playing their instruments in the same rhythm. 

• Polyphonic – In this case, independent musical parts overlap.

• Monophonic – In this scene, a single musical line is played.

• Accompanimental – It means accompanying a good quality.

Voice Timbre

If you look at the above context, it explained to you the real-life application of a timbre. As a singer, it is crucial to understand the different types of vocal timbre. We also call these the five-voice types. Now, let’s understand different types of timbre in voice timbre:

• Soprano – These singers sing in very high octaves.

• Mezzo – These singers sing in the middle range.

• Alto – Alto is the lowest of the female voices. 

• Bass – It is very broken up by high and low voices.

• Tenor – It is a male voice type.

• Contralto – We consider this voice as a middle voice.

• Treble – It is a word for a child’s voice.

These are also known as vocal timbre because they help us to identify various voices coming through a medium with the same frequency.

Dark Timbre

A novice person singing with a low voice is considered to have a dark timbre. We generally consider these terms in situations where a singer uses a low voice while singing at a concert for the first time in public.

However, dark tone is considered as the dark timber, whereas pop or rocky music is considered the light tone or the light timbre.

So the way you use your mouth can vary or alter the sound that is projected from your voice.

Timbre in Music 

You might have seen that musicians create varying timbres based on both their instrument and the number of frequencies the instrument creates.

You must have noticed that each note from a musical instrument is a complex wave comprising more than one frequency. So, the way you play an instrument affects its timbre.

In simple words, an experienced guitarist will have timbre, and for a starter, timbre would require some time. Henceforth, building a timbre requires the experience of playing an instrument.

Timbre in Music Example

One of the illustrative examples of timbre in music is “attack and decay.” When you pluck a guitar string or strike piano keys, the sound hits forcefully; it is loud and then after some time, the voice of the music dies away.

The above-mentioned concept of timbre in music explains how the same note can have a different timbre when played differently by another musician.

Do You Know?

Your voice has its own timbre. The unique soundwaves you produce while speaking is what ables you to be easily recognized by others.
