5.1 Arpeggio Sequencing Concept
Euclidean sequencing is a generative model which creates rhythmic note
pulses. Creating melodic patterns requires the introduction of pitch based
pattern generation. One of the models used to develop melodies in T-1 is
Arpeggiation. T-1’s parameters and setting build further onto these models.
What is an Arpeggio?
An Arpeggio is a musical term and is often described as a broken chord.
This means that a series of notes assembled as a chord, for example chord
C Major is divided into it’s individual notes C - E - G for playback. An
arpeggiator would play these individual notes in a predefined order across
a set octave range. This creates interesting repetitive patterns.
How are Arpeggios Applied in T-1?
There are many parameters that contribute to building advanced melodic
structures onto a Euclidean or step based pattern in T-1. At the most basic
level, building Arpeggios would start in the TONAL section with the Pitch
parameter. T-1 goes beyond basic Arpeggios and can generate more
advanced melodies. Pitch allows the assignment of notes into a chord. In
the tonal part of the SHAPE section voicing, range and style allow
arpeggios and more advanced melodies to be built.
• Pulses: A pulse is a note event which will trigger in a rhythmic
sequence. The melodic notes would be driven from these pulse
events and associated triggers.
• Pitch: Allows melodic notes to be selected into a chord using a
defined scale. These are the notes which will generate the melody.
• Voicing & Range: Amount of pitch variation applied.
• Style & Phrase: Behaviour of the pitch variation applied.
