A. 1. Ensure that you are in a quiet environment when trying to identify classical or instrumental music, as background noise can interfere with recognition. 2. Try to hold your device closer to the source of the music for better audio capture. 3. If the song is not recognized, consider using a different app that specializes in classical music recognition, as Shazam may not be optimized for this genre.

B. 1. Use Shazam in conjunction with other music identification apps to cross-check results. 2. If you frequently listen to classical music, consider providing feedback within the app to help improve its recognition capabilities.
