"text": "A chord progression is a series of chords played one after another. These patterns act as the foundation for harmony in many musical styles. You can find them in Western classical music and popular genres like pop, rock, and jazz. In these styles, the progression is the main feature that melody and rhythm are built upon.

These changes can establish a musical key or even contradict it. The key is the technical name for the tonality of a song. \n\nMusicians use different ways to write these patterns down. In classical music theory, they often use Roman numerals. A very common example is the I-V-vi-IV progression. In pop or traditional music, people often use the name and quality of the chords. For instance, a progression in the key of E major might be written as E major, B major, C minor, and A major. The letter tells you the root note, while the word \"major\" describes the chord type.

Musicians use Roman numerals to make it easy to change keys. A bandleader can ask a group to play the blues in B major instead of C. This makes it easy for a backup band to follow along. This pattern helped create many hits by artists like Chuck Berry and Little Richard.\n\nNot all songs are equally complex. Some funk songs focus on the groove and use only one chord. Other songs, like some punk tracks, use just a few chords. There is also the \"50s progression\" or \"doo-wop progression." + " It uses the chords I, vi, IV, and V. This pattern was used in the song \"Blue Moon\" from 1934.

Some jazz songs, called bebop, are much more complex. They might have a new chord change every single bar. This shows how much variety exists in music.\n\nSome progressions feel like they are moving in a circle. These are called circle progressions because they follow the circle of fifths. They use chords that have a special relationship to each other. For example, the sequence vi-ii-V-I moves in a way that feels very strong.

These patterns can help a song move to a new key. This movement creates a sense of travel through the music. It allows composers to make their songs feel rich and exciting.",
