Minor 7th Chords for Beginners: Hear the Softer Colour

Intro

A minor 7th chord keeps the familiar minor sound but softens its edge. It can feel warmer and less final than an ordinary minor chord. The name looks more complicated than the first two shapes you need: if you can already play Am and Em, you can turn each one into a minor 7th chord by changing a single note.

Start with your ears rather than a list of shapes. You are going to compare Am with Am7, then Em with Em7, before putting the new chords into a short progression. That way the name is attached to a sound you recognise, not just another fingering to remember.

Compare Am and Am7 on the same beat

Make your usual open Am chord. Keep the open fifth string as the bass note, fret the second fret on the fourth and third strings, and fret the first fret on the second string. Strum from the fifth string. Check each string separately if the chord is not clear.

Now lift the finger from the third string and let that string ring open. Leave the other two fretted notes where they are. This is open Am7. Alternate between the two chords every four beats: Am for one bar, then Am7 for one bar. Use the same strumming strength and the same part of the strings so you are comparing harmony rather than volume.

The open third string adds G to the notes of Am. Listen for the way Am sounds fairly settled and direct, while Am7 has a gentler pull. Do not worry if the difference seems small at first. Play one slow down-strum, let it ring for two seconds, stop it, then play the other chord. A little silence makes the comparison easier.

If you want another example of how one added note changes a chord's character, compare this exercise with major 7th chords for beginners. Major 7ths have a different colour, but the listening method is the same.

Make Em7 with one deliberate change

For open Em, fret the second fret of the fifth and fourth strings and strum all six strings. To make the simplest Em7 for this exercise, lift the finger from the fourth string. Keep the fifth string fretted and allow the open fourth string to ring. The open D is the minor seventh of E.

Play Em and Em7 in alternating bars. Keep the low sixth string under control because a heavy bass note can hide the small colour change above it. Try a soft brush across all six strings, followed by picking the sixth, fourth, third and second strings one at a time. The picked version often makes the added D easier to hear.

There are several useful Em7 fingerings, but learning more shapes will not help if this first contrast is still unclear. Stay with one change until you can predict the softer sound before you strum it. For a sharper seventh-chord comparison, listen to the stronger pull explained in dominant 7th chords for beginners.

Use a four-bar loop

Try this loop: Am7 for one bar, Em7 for one bar, F for one bar and G for one bar. Use four slow down-strums per chord. If full F is not comfortable, use the smaller F shape on the top four strings and keep the fifth and sixth strings quiet. The loop is a listening and chord-change exercise, so an untidy barre chord should not be allowed to take it over.

Am7 begins the loop with the soft colour you have just practised. Em7 keeps some space in the harmony, while F and G give the progression a clearer direction back towards Am7. Repeat it without stopping for two minutes. You can find more ways to organise familiar chords in common guitar chord progressions for beginners.

• ❯ Count four beats aloud before you begin.
• ❯ Change chord immediately after beat four, not during beat one.
• ❯ Keep each strum similar in volume.
• ❯ Stop and repair one buzzing string rather than squeezing the whole hand.
• ❯ Record four loops and listen for the return to Am7.

Fix the common shape problems

If Am7 sounds thinner than Am, check that the open third string is ringing. Your first finger on the second string may be leaning backwards and touching it. Move the thumb slightly lower, bring the first finger onto its tip and leave a small gap beside the open string.

If Em7 becomes boomy, lighten the attack on the lowest string. You can also begin the strum from the fifth string for one round, then add the low E again once the upper notes are balanced. The chord remains easy to fret, but easy shapes still need careful picking.

A late chord change is usually a preparation problem. After strumming Am7 on beat four, release the pressure but keep the fingers close to the strings. Move the finger that will fret the fifth string of Em7 first, then strum. Practise only that change ten times before returning to the loop. My guide to playing easy guitar chords cleanly covers the same string-by-string checking method.

Add the formula after you know the sound

A minor 7th chord contains the first, flattened third, fifth and flattened seventh notes of its major scale. It is often written as 1, flat 3, 5, flat 7. In Am7 those notes are A, C, E and G. In Em7 they are E, G, B and D.

You do not need to calculate that formula while changing chords. Its job is to explain what your ear has already noticed. Play Am, sing or hum its top note, then play Am7 and notice the open G within the chord. Repeat the process with Em and Em7. Naming the changed note makes the theory practical.

Finish with a musical strum

Once the four down-strums are steady, use a simple pattern: strum on beats one and three, then add a lighter up-strum after beats two and four. Keep the up-strums near the thinner strings. This lets the seventh colour speak without making the rhythm busy.

Do one final recording. On the first pass use plain Am and Em. On the second, use Am7 and Em7 while keeping F, G, tempo and strumming unchanged. The useful question is not which version is better. Listen for which one suits the mood you want.
