Chord Progression Difficulty Score

Paste a chord progression to get an estimated difficulty score, useful for gauging how hard a song will be to learn.

Each chord is scored by type: simple major and minor triads score lowest, chords like 7ths and sus chords score higher, and diminished, augmented, or extended chords (9th, 11th, 13th) score highest; chords built on roots that usually require a barre shape add an extra point. The average across all chords maps to an Easy, Moderate, Hard, or Very Hard estimate.

How to Use This Calculator

  1. Type or paste the chord progression, separated by spaces or commas.
  2. Click Score It to see the per-chord breakdown and an overall difficulty estimate.

This is a rough estimate based on chord shape complexity, not a substitute for actually trying the progression; a simple chord played at a fast tempo or in an awkward strumming pattern can still be difficult in practice.

Did You Know?

  • Many hit songs use only three or four simple open chords, which is part of why they’re approachable for beginning guitarists.
  • A capo can turn an otherwise barre-chord-heavy progression into an open-chord-friendly one in a different key.

Frequently Asked Questions

Does this account for strumming pattern or tempo?

No, this scores chord shapes only. A song with easy chords but a fast or syncopated strumming pattern can still be challenging.

What chord formats does this recognize?

Standard chord names like C, Am, G7, F#dim, Bbsus4, and similar; use the root note followed by any quality (m, 7, sus, dim, aug, 9, etc.).
