What you just heard
The trick is smaller than it sounds. Two of the three notes didn't move: C and G stayed put. Only the middle one dropped — a half step, the smallest distance in music — and became D#. Go back to the audio and catch the arpeggio note by note and stop at the second note. That's the one. Half a step separates a sunny day from a Monday morning.
Now it's your hands' turn
On the electric guitar a chord needs only a few clear notes — the amp sustains them and fills the space, so you mute the strings you are not playing and let the tone carry the rest. So the first position below is your way in — the position marked with ⭐ is the easiest to play. And do the exercise that's worth a whole lesson: C major, then Cm, then major again. Back and forth ten times, slowly. Your ear learns the difference before your brain does.

What is Cm?
Cm: C minor. The notes are C, Eb, G (fixed-do: Do, Mi♭, Sol) — the degrees 1–b3–5.
Where this chord lives
In real music, Cm works almost always as i in C minor, v in F minor, iv in G minor. In global pop it's the famous vi: the serious detour a chorus takes without leaving the key. You've heard it a thousand times; now you'll start noticing it.

Where it tends to go
Treating Cm as the home chord (I) of its key, it tends to go toward the pre-dominant (Dm / F) or the dominant (G / B°) — and the dominant pulls back home. It's a tendency, not a law.
When you want to go further
When it's time to improvise, C Dorian (C D Eb F G A Bb · 1 2 b3 4 5 6 b7: the minor scale with a major sixth — the minor that smirks); C Aeolian (C D Eb F G Ab Bb · 1 2 b3 4 5 b6 b7: the natural minor, the major scale's relative sibling); C Phrygian (C Db Eb F G Ab Bb · 1 b2 b3 4 5 b6 b7: the minor with a lowered second — a Spanish seasoning) work in full. The swaps below are the chord's cousins: different color, same job.

Improvising in context
To improvise over Cm as home, the C Aeolian scale covers it whole — it contains every note of the chord. And when the dominant (G) pulls back, the leading tone B is the note that wants to resolve home.
Swaps that work:
- Ebmaj7 — Relative major (♭III)
- F7 — It's the ii; resolves to this V
