How Feel and Key Affect the Chord Progression on AutoChords.com

On AutoChords.com, Feel decides which progression type you start from, and Key decides the actual chords you play. The site's own guidance is to pick a progression type that matches what you want to play, then pick a key you're comfortable playing in. If the result sounds too happy, switch the key to minor; if it sounds too depressing, switch it to major.

What "Feel" controls

Feel is the first choice you make, and it sets the character of the progression before any key is applied. The site describes it as picking "a progression type that matches what you want to play."

Two things follow from that:

  • Feel is about intent, not notes. You choose it based on the kind of part you're writing — a verse, a chorus, a moody loop — not on a specific chord.
  • Feel is not the only thing shaping emotion. AutoChords notes that your playing style can also affect the emotion of a chord progression. The same progression can read differently depending on how you strum, pick, or voice it.

If you don't have a Feel in mind, the site offers a Randomize! button, which skips the decision and generates a starting point you can react to.

What "Key" controls

Key is the second choice, and it does two jobs at once.

1. It determines playability. AutoChords points out that if you're playing guitar, the keys with the easiest chords are:

  • G major
  • E minor
  • C major
  • A minor

So key selection is partly a practical decision about what your hands can handle comfortably.

2. It determines how the progression sounds emotionally. This is where the major/minor distinction matters, and the site gives a direct rule for adjusting it:

If the progression sounds… Change the key to…
Too happy Minor
Too depressing Major

That's the fastest lever on the page. You keep the same Feel and the same shape of progression, and shift the mode to move the emotional register.

How the two work together

The flow is sequential: Feel first, then Key. Feel narrows you to a progression type; Key turns that type into concrete chords and sets the mood.

After that, the page gives you two more sections to work with:

  • Main Progression — your chosen progression in your selected key. Each chord shows its name, the notes in it, and an Edit / Export option.
  • Alternatives — the site uses the circle of fifths to suggest progressions that will probably sound good alongside the main one. The key may not match exactly, which makes these useful for building a chorus or bridge that contrasts with your main section.
  • All Chords in Key — every standard chord in your chosen key. Use this when you want to drop in an extra chord to vary the progression.

A practical way to use this

  1. Pick a Feel that matches the part you're writing.
  2. Pick a key you can actually play — on guitar, start with G, Em, C, or Am.
  3. Play the Main Progression and judge the emotion.
  4. If it's off, change the key to minor or major rather than rebuilding from scratch.
  5. Pull from Alternatives for a contrasting section, and from All Chords in Key for a single added chord.

The main thing to remember: Feel sets what kind of progression you get, Key sets how it sounds and how hard it is to play — and the major/minor switch is the quickest fix when the mood isn't right.
