Beside each instrument, there will be empty spaces.
You'll also see a separate section with various musical symbols (clef, sharps, flats, rests, etc.).
Match the symbols that are used to play each instrument and drag them to the empty spaces next to the corresponding instrument.
Puzzle 2: Identifying instruments from single symbols (one symbol per instrument)

You'll see a grid of squares, each containing a single musical symbol.
Below the grid, there will be a list of words with blanks.
Each blank corresponds to a musical instrument.
Identify the instrument based on the symbol in each square and fill in the blanks in the list with the instrument names.
For both puzzles, additional clues might be provided like:

The first letter of the instrument name.
The number of blanks corresponding to the number of words in the instrument name (for written answers).
Images of the instruments (for visual identification).
Do any of these descriptions sound like the puzzle you have in mind?
