Tango.info musical work code

Definition

A tango.info musical work code (TIWC) is a tango.info code that identifies a tango.info musical work.

TIWC can start with the letter T or with the letter Z.

• TIWC that start with the letter T are ISWC.
• TIWC that start with Z are not ISWC.
  • TIWC that start with the Z000 contain the SADAIC work number, e.g. the TIWC Z0000015621 contains the SADAIC work number 15621.
  • TIWC that start with Z but do not start with Z000 start with Z0999.

TIWC that start with the letter Z are not stable.
