================================ Representation: \*\*ordo ================================ | Humdrum Representation for Sequential Order =========================================== REPRESENTATION ~~~~~~~~~~~~~~ **\*\*ordo** -- sequential order of events representation DESCRIPTION ~~~~~~~~~~~ The **\*\*ordo** representation consists of a set of numerical values indicating the order of events. An **\*\*ordo** spine simply encodes a series of ascending integers marking the succession of events: ```` +------------+ | \*\*ordo | +------------+ | 1 | +------------+ | 2 | +------------+ | 3 | +------------+ | 4 | +------------+ | 5 | +------------+ | \*- | +------------+ The **\*\*ordo** representation recognizes "common system" barlines -- see `**barlines** `__. FILE TYPE ~~~~~~~~~ It is recommended that files containing predominantly ``**ordo`` data should be given names with the distinguishing \`.ord' extension. SIGNIFIERS ~~~~~~~~~~ The following table summarizes the **\*\*ordo** mappings of signifiers and signifieds. +-------+------------------+ | 0-9 | decimal values | +-------+------------------+ | . | null token | +-------+------------------+ | = | barlines | +-------+------------------+ | == | double barline | +-------+------------------+ *Summary of **\*\*ordo** Signifiers* EXAMPLES ~~~~~~~~ A sample document is given below: ```` +------------+ | \*\*ordo | +------------+ | =1 | +------------+ | 1 | +------------+ | 2 | +------------+ | 3 | +------------+ | =2 | +------------+ | 4 | +------------+ | . | +------------+ | 5 | +------------+ | \*- | +------------+ PERTINENT COMMANDS ~~~~~~~~~~~~~~~~~~ The following Humdrum command produces **\*\*ordo** data as output: +----+--------------------------------------+----------------------------------------+ | | `**num** <../commands/num.html>`__ | number selected Humdrum data records | +----+--------------------------------------+----------------------------------------+ TANDEM INTERPRETATIONS ~~~~~~~~~~~~~~~~~~~~~~ The following tandem interpretations can be used in conjunction with **\*\*ordo**: +--------------------+----------------+ | meter signatures | ``*M6/8`` | +--------------------+----------------+ | key signatures | ``*k[f#c#]`` | +--------------------+----------------+ | key | ``*c#:`` | +--------------------+----------------+ | tempo | ``*MM96.3`` | +--------------------+----------------+ | timebase | ``*tb32`` | +--------------------+----------------+ *Tandem interpretations for **\*\*ordo*** SEE ALSO ~~~~~~~~ `` barlines, **date, **dur, **metpos, **recip, scramble, **takt, **time, **Zeit`` -------------- |
