What you need to know about music


    Musical intervals indicate the pitch ratios between two sounds, and if you want to understand everything there is to know about music, you must stop at what musical intervals signify. In other words, they can be either simple or complex (e.g. the third, fourth, fifth, sixth, seventh and eighth), as well as perfect or imperfect.

Those with an interest in music should be well-versed in the vocabulary of the discipline. The interval is one of the most crucial. In the following, we’d like to discuss him in detail. If you haven’t had much exposure to music before, this material may appear a bit esoteric at first. However, if you have the openness and want to learn, you will be able to make sense of it.

What do you mean by intervals in music?

If we talk about music, we can’t do so without mentioning intervals. These have been taught by the ancient Greeks since the Middle Ages, and the discipline known as Intervalica described them at the time.

A musical interval, as defined by various authorities across time, is a difference in pitch between two sounds. The consonant is important in such an element. It shows itself when dealing with fractions of a whole number, and it brings harmony and stability to the equation.

There are two parts to an interval in music: the low sound, often known as the base, and the loud, high-pitched sound, more accurately known as the peak.

How do you find an interval in a graph?

To recognize intervals, you must know two things: the numerical size (the number of notes in a range) and the quality of the interval (number of tones and semitones).

To accomplish this, set a number on each line of the laptop or space and begin counting from there.

  • the distance between musical notes

The interval’s size is determined by the number of steps between the bottom and the top. Simple and compound components are both applicable to musical notes.

  • Within an octave, simple intervals are formed:In the first instance, the same sound is repeated, thus the notes are identical; in the second instance, we’re talking about two successive sounds that are situated on neighboring rungs. The tiny one has a semitone and is labeled 2m, whereas the second large one has a tone and is labeled 2M
  •  Third, we’re dealing with an extremely significant interval in music since it aids in the formation of a tonal range. It’s used to indicate the passage of time between three successive noises. There are four successive sounds that are examined in this situation: two tones in major, a tone and a semitone in minor, and a fourth tone. We refer to an interval as a perfect
  • quarter if it contains just two tones and a semitone; a moving quarter if it contains three tones; an expanded quarter when it contains three tones and a semitone.
  • fifth is an interval made up of five successive sounds, as the name implies. Three semitones are ideal; four is decreased; four is raised when there are four semitones; five is perfect if there are five semitones.
  • sixth – in this instance, there are six successive noises that make up the word. Here again, like in the third case, it’s a typical range interval. The four-tone sixth is referred to as huge, whereas the four-tone sixth is referred to as tiny. It may go in either direction.
  • seventh – the seventh is the step that is brought to light after seven other steps have been mentioned. Depending on the amount of tones and semitones, it might give the range a major or minor sound. In a major seventh, there are five tones plus a semitone; in a minor seventh, there are five tones plus no semitone.
  • Optave is an interval of eight notes that leads to a perfect pitch range.

Simple intervals can be joined to produce compound intervals, and this is how they are formed. The following are the names for musical ranges that go beyond an octave:


  • ninth – There are nine steps in this process.
    Steps 10 and 11 are the same as Steps 12 and 13 are the same as Steps
  • quarter – 14 steps fiftieth – 15 steps tertiadecima — 13
    Musical interval types

When discussing musical intervals, there are various types to consider, as seen above:

This is what we get when we multiply the number of semitones by the number of tones.

intervals that are precisely right (P)

All three quarters (4P – 2T + 1ST) and five tonalities (5P – 3T + 1ST) include them as well, as do the octaves (8P – 6T).

intervals that aren’t ideal

They can be big (M) or tiny (S) depending on their size (m). The following are the time intervals: small second (2m – 1 ST), big second (2m + 1T), small third (3m + 2T), big third (3M + 2T), small sixth (6m – 4T), big sixth (6M + 4T + 1ST), and small seventh (7m – 5T + 1ST). Small second is the second time interval, and large second is the time interval with the largest time interval.

As you can see, adding a semitone increases the perfect and big intervals, while subtracting a semitone decreases the perfect tiny intervals.

In addition, intervals are classified and the notes are sung in a certain way. They might be any of the following:

ascent; ascent and ascent (descending).

Exercises with intervals

To familiarize yourself with and improve your comprehension of these words, grab a notepad and attempt to construct certain intervals from there. Additionally, to assist you in comprehending everything, you may discover a variety of films on YouTube. Additionally, on this platform, you will have the option to view additional films in which you will be taught through pictures and sounds exactly how these critical parts of music work.

If you truly desire to play certain sounds, you may do it most simply using a synthesizer, an organ, a piano, or similar keyboard-equipped instrument. Such items are available for buy online, and we urge you to do so since you will benefit from several benefits such as: competitive pricing, regular discounts, a diverse product variety, rapid delivery, time savings, and 24/7 availability.
