What notes can I play over these chords?
Begin with the notes in each chord, especially its third. Those notes give you reliable landing points. Use neighboring notes to travel between them; a scale is a map of possibilities, while the chord change tells you where the phrase can land.
Hear each chord in the line
Over Am, A, C, and E are stable notes. Over F, F, A, and C are stable. A and C can stay in place across that change, while E moving to F reveals the new chord clearly.
A note outside the current chord is not automatically wrong. It may be a passing tone, a suspension, or a deliberate tension. Pay attention to duration: a quick passing note behaves differently from a held note on a strong beat.
Use a scale without becoming trapped by it
If a progression stays in a key, its scale can give you a practical set of nearby notes. But running the scale in order rarely says much about the chords beneath it.
Aim for one chord tone at each change, then connect those points with rhythm, repeated notes, and silence. Sing the phrase first if the fretboard pattern begins to take over.

Follow one chord change
Chords: | Am | F | Melody: E – G – E | F – A – C
E is part of Am. F announces the move to F major; A and C belong to both chords. G is a brief color between chord tones, not a required new harmony.
Try this
Hold E over Am and move it up a semitone to F as the chord changes. Then try keeping A over both chords and listen to the difference.
