What is a chord progression?

A chord is a collection of notes that create harmony by playing them together. A chord sequence, played one after the other, is called a chord progression. There are many types of chord progressions, each with a specific direction. Progressions are for chords what melodies are for notes. By listening to a chord progression, you can hear and detect the harmonic structures and intervals. Understanding the relationship between chords and different progressions also expands your ability to compose an accompaniment. If you want to practice this, we suggest using an online chord progression generator.

This tool allows you to easily find the key of a chord progression you generated, or extract it from existing tabs/chords you copied/downloaded from a sheet music site.

What is the key of a chord progression?

To start writing songs based on chord progressions, we must first understand that each key has a series of chords that belong to it.

The scale is, of course, a series of tones arranged in height. In European music, there are two main scales - major and minor, with many variants. Each scale is based on a tonic, to which the melody aspires. Such scales are called "diatonic", that is, they are made up of combinations of semi-degrees (corresponding to the difference between two adjacent piano keys) and whole degrees (corresponding to the difference between each other key).

The easiest way is to find the key in which a chord progression was composed is to use a Key finder tool, like this one, if you have the chord progression in text format.

How to recognize chord progression by ear?

First, you hear the chord, you pause, you find it on the guitar or any other instrument and you write it down. If it doesn’t work at first, don’t give up. Just listen and imagine what image the chords give you in your head or what the sound of the chord reminds you of. It can happen that you hit everything from the first, but it is very difficult. You may also hear them on the guitar and not with other instruments. And that's ok. It can also happen that you don't remember how they sound, and that's ok, as long as you can find them with the instrument, it's okay. You can use a chord progression generator online as well when practicing.

Some people need up to 5 years to recognize them. So don't let it demotivate you. Once you detect the chords, you're good to try finding the key.

What is the most common chord progression?

Bigger from relatively small. This is the basic progress of two chords coming and going. Each large chord has a relatively small one. The minor in question has the same retained and flattened notes but ordered differently. For example, the relative minor of C major is A minor: C notes are C, E, G and there are no sharp ones. The notes of the minors are A, C, E (Am). The only difference is between the G and A, which are separated by two semitones. However, the sound effects of this change are remarkable. The introduction and verse of Paul McCartney's "Hope for Liberation" contain progress from greater to lesser relative.

What is a three-chord progression?

The three-chord progressions originate from the major scale, for example, I-IV-V chords in a major scale. These three chords founded the beginnings of the blues and many other popular songs, as well as many careers. It doesn't always have to be the order I IV V, these are just three-chord progressions from which it started somewhere. In addition, there are three so many different three-chord progressions, such as I-II-V, I-II-IV, I-II-III, etc.

How long is a chord progression?

How long the chord progression will last depends on the song itself. If the song is fast we will see that we have as few chords as possible played on the fretboard (for example 4 or 5), ie. the faster our tempo, the less frequently the chords will change. When there are many chords in a fast song, there is a high probability that the harmony will be easily disturbed and the song will not sound nice. On the other hand, long progression is more used in slower songs, or ballads, but that's not a general rule at all. This slow shift of chords will change the atmosphere or "mood" of the song so that the lyrics are more in tune with that melody than some heavier, or dance music.
