to improvise upon - three programs for a brain (1999) by Peter Heeren published on 2023-10-19T14:26:55Z I: Begin an improvisation spontaneously on your instrument. Pay attention to the audience's reaction and stop if they become restless. Practice this improvisation rarely, or preferably not at all. Start with softer instrument registers, and switch to preferred registers during the improvisation. Play a melody with your left hand. Use specific note values at the beginning and introduce other values, but less frequently, later. Vary the rhythm, avoiding repeated patterns initially, and introduce them later. Initiate the improvisation at a slow tempo, accelerate towards the end, and return to a moderate tempo. Limit yourself to notes in the range of C0 to G1. Employ major seconds and minor thirds for ascending melodic steps, and major seconds and perfect fourths for descending ones. Towards the end of the improvisation, transition to minor seconds and perfect fifths for ascending melodic steps, and major seconds and minor sixths for descending ones. Avoid tritones and major sevenths. Optionally, play chords in your right hand on a different manual. II: Play two-voice chords in the middle register with crossed hands. Utilize a manual with a Principal 4' register. Play the chords aimlessly until you perceive their interval combinations. When disliking a chord, play individual tones and remember them. If you encounter the same unliked chord again, play a half step below the previously remembered note. Repeat interesting, unliked chords two to four times and observe your preferences. Take breaks when highly excited or interested. Conclude the improvisation if you very much like a chord or if you become fatigued. III: Improvise in the style of Mozart and record it using a sequencer. Incorporate trills frequently. Select three to five measures from the recorded performance, preferably with trills, the day before the performance, and sight-read them. Use only the second finger of each hand. Vary note values and rhythm, including repeated patterns. Begin at a slow tempo, accelerate suddenly towards the end of the last third, and return to a moderately-paced tempo. Restrict yourself to notes within the range of C0 to G1. Employ major seconds and minor thirds for ascending melodic steps and major seconds and perfect fourths for descending ones. Towards the end of the improvisation, switch to minor seconds and perfect fifths for ascending melodic steps and major seconds and minor sixths for descending ones. Avoid tritones and major sevenths. Optionally, play chords with your right hand on a different manual. Genre Classical
