What is a popular chord progression? Chord progressions are actually series of chords which are played one after the other to produce a harmonious tune. By now you have learned the different piano chords and may have memorized them a bit. The knowledge you have about chords will help you a lot in playing the piano. Here is the reason why…
When you look at a music sheet, did you notice that there are certain chords that loop around the entire music piece? These chords follow the popular chord progression loop. They are said to be popular because you cannot only find them in one music sheet but also in other compositions. The only differences they have are the time signatures and the notes being played on the music sheet.
How are this popular chord progression written? They can be written in two ways. One is through the Roman numeral system and the other one is by the simple use of numbers. The basic chord progression is called the “three chord key” or “3-note triads” which is comprised of three chords that when played together, creates a harmonious melody.
The most basic and popular chord progression is I – IV – V or 1 – 4 – 5. Take the key of C for example, if it follows this chord progression, you will have C – F – G. After playing the third chord of the chord progression order, you will loop around and go back to the first chord. Sometimes one of these chords will be changed into a minor chord that hymns together with the major chords, other times some composers insert the minor chords instead of just changing one of the major chords.
I – IV – V can be changed into I – ii – V which stands for C – Dm – G. Notice the smaller Roman numerals are used to represent the minor chords such as the D minor. However, most composers use numbers instead of the roman numerals. An example for this is the 1 – 6 – 2 – 5 popular chord progression which represents C – Am – Dm – G7. Your guide in order to learn chord progression will always be your knowledge of the fifteen key signatures as well as the different piano chords that’s why it is so important for you to memorize those basics.
