<remarks xml:lang="en">
<p>On a wind instrument, the "highest note possible" depends on the player’s abilities.
On
a string instrument, the "lowest note possible" depends on how much a string is
de-tuned; that is, loosened using the tuning peg. Use of the <att>pname</att> and
<att>oct</att> or <att>ploc</att> and <att>oloc</att> or <att>loc</att> attributes is
necessary to record the written pitch and octave of the symbol for this note.</p>
