Chord Progression Generator

Generate common chord progressions in any key. Choose a key and progression pattern to create musical chord sequences.

How to Use This Calculator

  1. Select the key you want your progression in (C, D, E, etc.).
  2. Choose a progression pattern from the dropdown (I-V-vi-IV, I-vi-IV-V, etc.).
  3. Click "Generate Progression" to create the chord sequence.
  4. Use the generated progression in your compositions, practice, or music theory study.

Chord Progression Theory

Chord progressions use Roman numerals to represent scale degrees:

I = Tonic (root chord)
ii = Supertonic (minor)
iii = Mediant (minor)
IV = Subdominant (major)
V = Dominant (major)
vi = Submediant (minor)
vii° = Leading tone (diminished)

Example: I-V-vi-IV in C major means C (I) - G (V) - Am (vi) - F (IV). This pattern works in any key.

Full Description

Chord progressions are sequences of chords that form the harmonic foundation of songs. Understanding common progressions helps musicians compose, improvise, and analyze music. Progressions are often described using Roman numerals representing scale degrees, making them transposable to any key.

The most famous progression is I-V-vi-IV (used in songs like "Let It Be," "No Woman No Cry," and many others). Other common progressions include I-vi-IV-V (the 50s progression), vi-IV-I-V (common in modern pop), and ii-V-I (essential in jazz). Each progression has a distinct emotional quality and is used in different musical contexts.

This calculator generates common chord progressions in any key. Select a key and progression pattern, and it creates the actual chord names for that key. Use it to learn music theory, find progressions for your compositions, or practice playing progressions in different keys. Understanding chord progressions is essential for any musician.

Frequently Asked Questions

What are common chord progressions?

I-V-vi-IV (C-G-Am-F) is the most popular progression, used in countless songs. I-vi-IV-V (C-Am-F-G) is the 50s progression. vi-IV-I-V (Am-F-C-G) is common in modern pop. ii-V-I is essential in jazz.

What do Roman numerals mean in chord progressions?

Roman numerals represent scale degrees. I = tonic (root), ii = supertonic, iii = mediant, IV = subdominant, V = dominant, vi = submediant, vii = leading tone. Uppercase = major, lowercase = minor.

How do I use chord progressions in different keys?

The progression pattern stays the same, but the actual chords change with the key. For example, I-V-vi-IV in C is C-G-Am-F, but in G it's G-D-Em-C. The calculator generates progressions in any key.

Can I create my own progressions?

Yes! Start with common progressions as a foundation, then experiment. Try substituting chords (like using ii instead of IV), adding 7ths, or using inversions. The calculator helps you understand the patterns.
