In what was surely a nose-tweak at those fooled by this imposture, Casadesus also reported that "The upper stave is notated in D, the lower in E". Since the violin is not a transposing instrument, there would have been no obvious technical reason for the upper staff to be written in a different key from the lower staff, especially for what sounds more like a short score than a completed score.
The apparent discrepancy between the key of the upper and lower staffs of the piece, especially considering its short score format, raised questions about the authenticity of the composition.
