Despite publication of revised editions of orchestral repertoire, many scores and parts still contain significant errors. Norman del Mar's Orchestral Variations (Eulenburg, London, 1981), studies 45 works: newer editions have made some chapters obsolete (e.g. Jonathan del Mar's edition of Beethoven symphonies); most remain valid. 29 works, e.g. Debussy, Prélude à L'Après-midi d'un faune) are treated thoroughly in the US Conductors Guild Journal and on-line here.
The list below has errors found during preparation and rehearsals for concerts. Inquries and contributions are most welcome via the Contact form. Please give details of edition and your contact details. A credit and link will be given here for verified contributions.

Figure 8 (4/8): crotchet = 80 should read quaver = 80 in f.s., v.s. and parts.
Figure 10, 5th bar: first violins, final note (F#) should be 8va, like rest of bar.

17 after [E]: Timpani has one bar's rest on the first bar of phrase. Double bass and bassoon 2 have A crotchet at start of this bar, continuing for the rest of the phrase. This is the only bar in which this happens, and appears to be an anomaly in the timpani part and full score.
2 before[X]: Timpani and score change rhythm to place the four quavers on the beat, instead of being syncopated as in the rest of the phrase. There is no musical reason for this to happen, nor other examples in the work, suggesting it is an error.
