Triangle Percussion Instrument - Classic Musical Tool with Mallet #3514874 (License: Personal Use)

This image shows a hand-drawn depiction of a standard musical triangle: a hollow, equilateral metal bar bent into a triangular shape with an open corner, allowing it to vibrate freely. A small loop at the apex suspends the instrument, while a soft-headed mallet lies alongside for striking. The joints along the sides suggest reinforced points or decorative elements, common in vintage illustrations.
