Chord Progressions – What Exactly are Chord Progressions

Chord progressions are a sequence of chords played in a particular pattern in order to harmonize the melody. They are used to form the basic framework of a song. In most cases, chords share at least one note with the next chord in the sequence.

Chord progressions are based on a particular scale, and the notes of each chord are usually taken from the notes of that scale. The most frequently used chord progressions are based on the first, fourth, and fifth scale degrees. The first degree is referred to as the tonic, the fourth is called and subdominant, and the fifth is labeled the dominant.

These scale degrees are most often written as roman numerals. The tonic is written as a I, subdominant as a IV, and the dominant is the V. To differentiate the difference between major and minor chords, lower and uppercase roman numerals are used. Uppercase roman numerals such as IV and V denote major chords. Lowercase roman numerals such as

How To Play Piano Using Chord Symbols

Chord symbols (for example, Cmaj7 or G6) are a type of notation used frequently in jazz and other areas of modern music to notate chord progressions and changes. This type of notation differs from that of classical music in that chord symbols don’t show the function of a chord the way the Roman numeral notation does.

Chord symbols, for modern music with lots of changes, are much easier to read. They function as a sort of shorthand for change-heavy music and are written with four chord parts in mind: the root, the quality, the extension, and the alterations.

The first part in chord symbols, the root, tells the musician which note is the root of the chord. In an E6 chord, for instance, the E serves as the root. Chord symbols also allow for inverted chords, or chords with a root other than the bass note. These chord symbols express that by showing the bass note with a diagonal slash under the original symbol.
