TIME DIMENSION

This node allows us to go deeper into the rhythm of the music. We introduce you to the basic concepts of the temporal dimension, its elements and sets, monorhythm, temporal scales and polyrhythm:

INDEX OF Node 1: the rhythm

1. Temporal dimension: allows us to define the durations of sounds and place them in time. It is represented by a numbered horizontal axis where the time elements are arranged.
   1. Beats: are the unit of measurement of the time dimension, a constant base that marks the metronome. They allow us to define the speed of the composition (beats per minute, or PPM), on which we build musical rhythms.
   2. 
      Temporal formula:
      This formula mathematically expresses the relationship between speed, time and length of a musical idea. It is a very useful tool to synchronize our musical piece with the duration of a piece or audiovisual segment.
   3. Temporal fractions: Allows us to increase or decrease the speed of the pulses, subdividing or grouping pulses. These fractional pulses have their own numbering and are related to the reference pulses through a cycle.
      1. Types of fractions: we distinguish between simple and complex fractions, depending on whether or not they contain the number 1 in the numerator or denominator.
      2. Types of effect: Fractions can produce 2 types of effects: slowing down or speeding up our original speed.
      3. Place of application: It is important to know when and where we apply fractions: punctually within a segment or throughout a voice in a fixed manner.
         
   4. Modulo-compasses: the measures are used to organize the temporal dimension in modules, facilitating the notation and localization of the temporal elements thanks to the modular numbering.

1. 
   Monorhythmia
   Monorhythmia is the minimum musical expression of the temporal dimension. It consists of compositions with a single rhythmic voice.
   1. 
      Pulse
      It is the basic element of position of the temporal dimension. Locate each note or rest on the timeline.
   2. Temporal Interval (iT): this basic element defines the distance between 2 selected pulses, i.e. the duration of each note or rest.
   3. sets: they are sequences of P and iT.
   4. Rhythmic design: it is a proposal to start exploring the creation of different rhythmic voices, which are the basis of polyrhythm.
   5. Temporal parameters: they analyze rhythmically the voices, extracting rhythmic information very useful for the understanding of the structure of the voice, and for the creation process.

1. Timescales (TS): A totally new and developing concept. In the same way that we use sound scales, in the temporal dimension we can also create temporal scales, from collections of Pulses.
   1. parameters defining the TE: The parameters of the Time Scales help us to specify its different characteristics: the length of the TE, its number of repetitions, the rotation, its number of degrees and its structure.
   2. ET elements: are the ingredients of ET: time degrees (ºT) and time degree intervals (iºT), and indicate a position or a distance.
   3. sets of TE: they are successions of ºT and iºT.

1. Polyrhythm: consists of a rhythmic idea formed by the superposition of different rhythmic voices, allowing the development of rhythms with a great variety of nuances.
   1. the cycle: it is the result of superimposing different rhythmic voices in a determined duration: each voice develops in a different way, but they begin and end at the same time. The cycle gives us a global vision of the rhythm we are developing.
   2. polyrhythmic modes: they are a totally new and developing concept. They are a proposal of polyrhythm, to begin to explore the combination of different rhythmic voices.
