Mola Errata List Jun 2026

While some conductors or principal players may have personal notes, the MOLA errata list provides a standardized, peer-verified source for known errors. As noted by Polyphonic Archive , the database contains roughly 900+ titles. 3. Professional Standards

For the first printing and some Kickstarter fulfillment copies, minor component issues were noted:

When modeling a truss, software assumes nodes are frictionless pins. In a Mola model, the metallic balls and magnetic ends create slight friction. This friction adds a small amount of rotational resistance, making a Mola truss slightly stiffer in real life than an ideal mathematical truss model. 5. Best Practices for Managing Mola Discrepancies

| Pattern / Page | Location | Error | Correction | |----------------|-----------|-------|-------------| | Fish Mola (p. 12) | Step 4, cutting diagram | The dorsal fin cutout shape is shown reversed (mirror image). | Use the corrected template available at [URL/QR code]; or cut as a mirror of the printed shape. | | Bird Mola (p. 18) | Materials list | Missing black fabric for the eye detail. | Add 2" × 2" black cotton. Eye appliqué requires black layer under top orange layer. | | Turtle Mola (p. 24) | Stitch diagram | Arrow indicating "blind hem stitch" points to wrong edge. | Stitch should catch the folded edge of the top layer only; corrected diagram online. | | Geometric Border (p. 31) | Color key | Colors swapped for olive green and dark brown. | Olive = Layer 2; Dark Brown = Layer 3 (the opposite of printed key). |

Reality: While Mola mola can grow up to 3 meters (10 feet) in length and weigh up to 2,300 kilograms (5,070 pounds), it is not the largest fish in the world. The whale shark (Rhincodon typus) holds that title, reaching lengths of up to 20 meters (66 feet).

This level of detail ensures that any librarian can quickly find and fix the error, regardless of which orchestra originally discovered it. While some conductors or principal players may have

By identifying errors before the first rehearsal, the conductor does not need to stop the orchestra to fix a part.

Classical scores, even those from prestigious publishers, are often riddled with "ghost notes," missing rests, or incorrect pitches. For an orchestra, discovering these errors during a rehearsal is a disaster—it wastes the time of 100 expensive musicians. Key Features of the List

A is a specialized document or database maintained by the Major Orchestra Librarians’ Association (MOLA) that identifies and corrects errors in published musical scores and performance parts. These lists are essential tools for orchestra librarians, as they ensure that performances remain faithful to the composer's intentions by resolving inconsistencies before they reach the stage. The Role of MOLA Errata Lists Professional Standards For the first printing and some

Even standard repertoire, such as the Beethoven symphonies, can have errors in the original or reprinted editions. Without a centralized list, librarians in different orchestras would waste countless hours finding the same mistakes, comparing parts to the score, and fixing them.

: Corrections are typically organized by instrument, rehearsal figure, measure number, and beat to provide clear, actionable instructions for librarians.
