"Volume swell" diamond over a note ??
In the symbols pallet, there is an articulation symbol called a "Volume swell". It looks like a diamond over top of a note.
(1) Why is a volume swell listed as an articulation rather than as a dynamic? Another way to ask this is "What is the difference between a volume swell and a cresc-decresc hairpin pair?"
(2) Since it is essentially a dynamic, should it be placed over the note, or below the staff with other dynamics symbols?
(3) Is this diamond a standard music notation? I have searched the internet, and cannot find any reference to it.
I often swell a note on flute, but I probably should not use a symbol that few people know about. WDYT?
To me, the symbol called "Soft accent above" looks more like a swell to me than the diamond does. But it sounds like that symbol is already taken for a different use.
