Why does e.g a C Major Chord sound different from a F Major Chord ? Is it only the absolute Height of the Root ?
The intervals might be the same, but they start off from a different frequency. You can see here the different frequencies for the notes.
For instance, the C major that starts from C1 will have these frequencies:
- C1: 32.70
- E1: 41.20
- G1: 49.00
And similarly, for the first three tones of F major from F1:
- F1: 43.65
- A1: 55.00
- C2: 65.41
You see that will the intervals might be the same (major 3rd and then minor 3rd), when you start from a note that is lower or higher, the frequencies will not be the same and thus they will not sound the same
