Does “high quality recording or photo” mean it should be commercial?
No, it means that your recording or photo was engineered or photographed in a proper environment with proper equipment. The quality should be clean and clear. Singers should not sing acappella unless the song is written acappella. The recording cover or back of the photo should have a neatly typed label that includes name, title of piece(s), name of the accompanist and contact information. The recording and photo should sound and look like you now (not 15 years ago). The recording and photo should not be altered to what you wish you sounded like now. ‘Commercial’ means your recording or photo is/was for sale. A recording or photo does not need to be for sale to be considered ‘high quality’.
