Root position
F – Ab – C – EbThe root F is the lowest note. This is the shape most people learn first.
4 notes · 1 · ♭3 · 5 · ♭7
Fm7 is built from F, Ab, C and Eb — the formula 1 · ♭3 · 5 · ♭7, or 3, 7 and 10 semitones above F. The shape uses 2 white and 2 black keys, and you can hear it, invert it and compare it below.

Chord tones
A minor seventh chord adds a minor seventh above a minor triad. It keeps the darker colour of the minor third, but the extra note softens the edge, so the chord feels relaxed rather than sad. Minor sevenths are the natural seventh chords on the second, third and sixth degrees of a major scale.

Step by step
Inversions
An inversion keeps the same 4 notes and simply moves the lowest one up an octave. Learning them means you can change chords with small hand movements instead of jumping to a new part of the keyboard.
The root F is the lowest note. This is the shape most people learn first.
Ab is the lowest note, so the minor third sits in the bass and the notes below it move up an octave.
C is the lowest note, so the perfect fifth sits in the bass and the notes below it move up an octave.
Eb is the lowest note, so the minor seventh sits in the bass and the notes below it move up an octave.
In context
In D♭ major the chord functions as iii7. Altogether it is produced by the scales of 6 keys, so learning it once pays off in several places.
Chord tones are spelled by the degree they occupy, so the third of a minor chord is written as a flat rather than a sharp even though it is the same key on the piano. A double sharp such as F## means the key one whole tone above F.
Compare
Fm7 and F7 share F, C and Eb. Moving the major third A down 1 semitone to the minor third Ab turns F7 into Fm7.
Practise the pair together: hold the shared notes F, C, Eb still and move only the one finger. Hearing that single change is the quickest way to recognise the two chords by ear.
Open F7 →Good questions
Fm7 contains F, Ab, C and Eb. Counted from the root, that is the formula 1 · ♭3 · 5 · ♭7, or 3, 7 and 10 semitones above F.
A comfortable beginner fingering is 1 (thumb) on F, 2 (index finger) on Ab, 3 (middle finger) on C and 5 (little finger) on Eb. Finger numbers run from the thumb (1) to the little finger (5), and they change once you start using inversions.
Fm7 and F7 share F, C and Eb. Moving the major third A down 1 semitone to the minor third Ab turns F7 into Fm7.
It occurs naturally in D♭ major (iii7), E♭ major (ii7), A♭ major (vi7), C minor (iv7), F minor (i7) and B♭ minor (v7). The roman numeral shows which degree of the key the chord is built on.
root position is F – Ab – C – Eb, first inversion is Ab – C – Eb – F, second inversion is C – Eb – F – Ab and third inversion is Eb – F – Ab – C. Every inversion holds the same notes; only the lowest one changes.
