How to clear The Singing Dragon request in New Pokemon Snap
Guide:
Visit the Fireflow Volcano.
A little ahead in the main course after going down the narrow path, you’ll hear high pitched singing.
Play the melody as soon as you hear the singing, and stop the melody when the singing stops.
After the music stops, a flock of Altaria will be seen flying overhead. Take a photo to fulfil the request.
