Example:


Note la = new Note( tu.noteToFreq ( T5Notes.LA, 3 ),125,1,1,50,false);
Note la2 = new Note(tu.noteToFreq ( T5Notes.LA, 3),250,1,1,90,false);
Note la3 = new Note(tu.noteToFreq ( T5Notes.LA, 5 ),250,1,1,100,false);
Note la4 = new Note(tu.noteToFreq ( T5Notes.LA, 3 ),250,1,1,200,false);
Note la6 = new Note(tu.noteToFreq ( T5Notes.DO, 6 ),250,1,1,200,false);
Note la7 = new Note(tu.noteToFreq ( T5Notes.MI, 4 ),200,1,1,100,false);
Note la5 = new Note(tu.noteToFreq ( T5Notes.SOL, 5 ),200,1,1,50,false);

Description:

T5Notes public interface contains two kind of Tactu5 constants.
The first ones refer to notes frequency in the 0 octave, for instance these two statements are equivalent:

float myFreq = T5Notes.A;
float myFreq2= 55.0000;

For mantaining formal clarity T5Notes interface provides enharmonic equivalence, so ...

float myFreq = T5Notes.F_SHARP;
float myFreq2= T5Notes.G_FLAT;

.. are the same too.
It's possible to use English notation ...

float tonic = T5Notes.C;
float thirdminor= T5Notes.E_FLAT;
float fifth= T5Notes.G;

... as well as Iitalian one.

float tonic = T5Notes.DO;
float thirdminor= T5Notes.MI_BEMOLLE;
float fifth= T5Notes.SOL;

French and German notations will be included sometime in the future ( maybe soon).

The second type of constants refers to scales and mode structure useful for generating chord and sequence with Tactu5Utility class. They are integers array describing modes intervals in semitones, for example:

iint[] minorScale = T5Notes.NATURAL_MINOR;
int[] minorScaleStructure = { 2, 1, 2, 2, 1, 2, 2 };
