Heinrich Heine? Pyotr Ilyich Tchaikovsky? Apocryphal?

Question for Quote Investigator: A popular adage comments on the comparative expressiveness of words versus music. Here are two versions:
- Where words leave off, music begins
- Music begins where the spoken word ends
Many people have been credited with this saying including the famous German poet and critic Heinrich Heine. Would you please explore the attribution to Heine?

This letter was sent more than two decades after the death of Heine; hence, its probative value is reduced. The lack of an earlier citation means that the attribution to Heine is currently weak. Yet, the discovery of earlier evidence, perhaps in German, could strengthen the linkage in the future.
Below are additional selected citations in chronological order.
