The Stradivarius violin is one of the most valuable and collectible musical instruments in history. To find an original in playable condition is a rare find. Many examples are insured for several hundreds of thousands of dollars. Not long ago, someone began attempting to create forgeries of the magnificent violin. Multiple dozens of examples made it into circulation with no one the wiser. However there was something wrong with the forgeries that revealed their nature. The end of the violin's neck is capped with a single wooden piece that is called the scroll. It holds the tuning pegs in place and works with the neck to keep the strings taught and playable. The scrolls of the Stradivarius were thought to be no more special than any other, as very few if anyone thought they contributed to the sound of the instrument overall. The truth of their importance came out hand in hand with the discovery of the forgeries. Whenever a C note was played on a true Stradivarius, it rang strong and pure as any other note on the instrument. However when a C was played on a forgery, the note had a lifeless, almost dull tone that was clearly uncharacteristic of the legendary instrument's reputation. The cause of this fault was very painfully examined and researched for months until the cause was identified. There was something wrong with the scroll that caused the sour note. Sure enough, all the forgeries were identified by testing them with the single note weakness that the true instrument would never have. In the end, several people were out hundreds of thousands of dollars, multiple investigations were launched, but nobody could determine who had made the forgeries. To this day, the entire episode is known as The Mystery of the Dead C Scrolls.
