Because, beneath the paint or finish of the door, it is made of ferrous metal and magnets stick to anything like that, as they contain iron.
In general, steel nails will not remain "joined" if a magnet touching them is removed. It is important to note that nails affected by a magnet retain a weak "impression" of the field and remain slightly magnetic. But the magnetic field "impressed" on the nails will be quite small and will not hold the nails together once the magnetic is removed.
That indicates the number of beats for which you hold the note.
The field is strongest on the poles of the magnet (the ends of the magnet). More specifically, the 8 corners of the magnet are where the strongest magnetic field will occur. The weakest field occurs in the center of the magnet.

If the magnets repel, it means that they positioned with same poles toward each other (North with North or South with South). If they attract each other, then it means that the near poles are different (North with South).
'On the front door was pinned a note.' Is a complete sentence.
Not normally. (Note Alco magnets as an exception.)
You hold your finger on the note you wish to play wile the other hand strums that string
You will note that the iron filings are clustering around the magnet in a pattern.
Usually if there is water/ice through the door it will have a filter. Some that have ice makers will also have a filter. Even if your refrigerator does not have a filter but does have an ice maker consider installing one in the water supply line, the installation can be a DIY task. Note: As an example of the style of water filter I usually install is linked below.
