List of compositions by Franz Schubert (doubtful and spurious)

This list details compositions attributed to Franz Schubert whose authenticity is either doubtful or entirely spurious. Attributions may be questioned for a variety of reasons, including the absence of a reliable manuscript source, stylistic inconsistencies with Schubert's known works, conflicting or incomplete provenance information, or documented evidence of forgery.

Doubtful Works:

These are compositions where the authorship by Schubert is uncertain, and further research may be necessary to confirm or refute the attribution. Possible reasons for doubt include:

• Lost Manuscripts: The existence of a work may be documented, but the original manuscript is lost, making verification impossible.
• Conflicting Attributions: Other composers have been suggested as the true author of the piece.
• Stylistic Anomalies: The composition exhibits musical characteristics not typically found in Schubert's authenticated works.
• Unreliable Sources: The only source of the attribution is a secondary or tertiary source of questionable reliability.
• Fragmentary Evidence: Limited or incomplete documentation exists to support Schubert's authorship.

Spurious Works:

These are compositions that have been definitively determined not to be by Franz Schubert. Common reasons for this determination include:

• Proven Forgery: Evidence demonstrates that the work was deliberately created and falsely attributed to Schubert.
• Misattribution: The work is demonstrably by another composer.
• Lack of any credible source: No reliable source ever connected the work to Schubert until a relatively late date.
• Stylistic Incompatibility: The composition's style is fundamentally different from Schubert's established musical language and could not reasonably be attributed to him.

Importance of Authentication:

Accurate attribution is crucial for several reasons:

• Scholarly Accuracy: Maintaining a clear understanding of Schubert's genuine oeuvre is essential for musicological research and analysis.
• Performance Practice: Performances of spurious works under Schubert's name can misrepresent his artistic output.
• Copyright and Legal Issues: Incorrect attribution can create legal complications regarding ownership and licensing of the music.

Challenges in Authentication:

Determining the authenticity of Schubert's compositions can be challenging due to:

• Schubert's prolific output: He composed a vast amount of music, some of which was never published or widely circulated during his lifetime.
• Limited surviving manuscripts: Many of Schubert's manuscripts have been lost or destroyed.
• Forgery and misattribution: The popularity of Schubert's music has made it a target for forgers and misattributions.

This list is not exhaustive and may be subject to revision as new evidence emerges. Consult scholarly catalogs and musicological research for the most up-to-date information regarding the authenticity of specific compositions attributed to Franz Schubert.
