210 APPENDIX B. PROGRAM LISTINGS */ 1 if playable, 0 if not. double playabilityLevel(Minimum m); /* Determines the playability level of a playable Minimum. The playability level is determined by the rules generated by M5'. The M5' rules are implemented in this function. In general, 3.0 is easily playable while 1.0 is difficult to play. Parameters: m: the Minimum to be analysed Returns: The playability level as a double. */ double strengthLevel(Minimum m); /* Determines the strength level of a playable Minimum. The playability level is determined by the rules generated by M5'. The M5' rules are implemented in this function. In general, 4.0 is strong and bright while 1.0 is weak and dark. Parameters: m: the Minimum to be analysed Returns: The strength level as a double. */ Minimum getCompletedMinimum(Minimum m); /* Creates a copy of a given Minimum with all empty fields initialised to the average values of the expert set (cf M5'). Parameters: m: the Minimum to be analysed Returns: A new Minimum with NaN fields replaced with expert set averages. */ void pitchCorrection(Minimum m); /* Corrects the pitch of a playable Minimum according to experimental results from a number of flutists. Parameters: m: the Minimum to be analysed */ void analyseMultiphonics2(Vector playableminv); /* Determines if any two note multiphonics are playable in a set of playable notes for a fingering. Multiphonics are defined as notes which are "not harmonically related" (see code for details). Ouputs the multiphonic if so. Parameters: playableminv: the set of playable minima for a fingering */ void analyseMultiphonics3(Vector playableminv); /* Determines if any three note multiphonics are playable in a set of
APPENDIX B. PROGRAM LISTINGS 211 playable notes for a fingering. Multiphonics are defined as notes which are "not harmonically related" (see code for details). Ouputs the multiphonic if so. Parameters: playableminv: the set of playable minima for a fingering */ int noteDistance(Minimum m1, Minimum m2, Vector playableminv); /* Calculates the distance in playable notes between two given minima. Parameters: m1: the first minimum m2: the second minimum playableminv: the set of playable minima for a fingering Returns: The number of playable minima between the given two minima, plus 1. -1 if error. */ int pitchIndex(Vector minv); /* Calculates the sum of squares of cents of the given minima. Parameters: minv: the set of minima Returns: The result of the calculation (0 if no minima). */ char* allNotes(Vector playableminv); /* Concatenates the note strings of the playable notes for a fingering, delimited by ';' Parameters: playableminv: the set of playable minima for a fingering Returns: The concatenated null terminated string */ int harmonic(Minimum m1, Minimum m2, Vector playableminv); /* Determines whether two minima are harmonically related. See code for definition of harmonic. Parameters: m1: the first minimum m2: the second minimum playableminv: the set of playable minima for a fingering Returns: 1 if m1 and m2 are harmonic, 0 if not. */ int inArray(int* array, int size, int num); /* Determines whether an integer is present in a given sized array of integers. Parameters: array: the array of integers size: the number of elements in the array
