Performance
- For 1 performer, acoustic and electric guitar, objects and real time digital processing of sound, mini speakers and amplifier. Sometimes piano and video.
- Duration variable (~45 min)
- Year: 2015
The performance is divided in two main sections: one for DSP and acoustic guitar with four algorithmic compositions and one for improvised electric guitar and objects
The algorithmic compositions: “Terra”, “Astronauta”, “Luna”, “Crononauta”
Astronauta
I used PD (Pure Data) for the audio processing, and a series of gestures are contemplated.
The PD indications: For 1 BT Anker A7910 speaker or similar, or 2 BT Anker speakers connected to AUX on sound card. One speaker remains on the table, the other is set upon the strings of the acoustic guitar to generate feedback.
GESTURE SEQUENCE:
- I. leave on speaker on the table, place the other one on the strings of the acoustic guitar, create minimal feedback extremely controlled.
- II. Move the speaker near the bridge up to the neck very slowly and listen to feedback.
- III. Start to manage feedback with the filters / eq on the acoustic guitar (B/M/T)
- IV. Play with the speakers ad-lib (use to tap muted strings, move closer together and away to generate and manage feedback, place speakers on guitar body).

Improvisation: prepared electric guitar and objects
I prepare the guitar with metal clips, springs, variously sized steel plates through the strings, using also chopsticks and steel washers as percussive objects.
I usually have a fixed sequence to start with and then change during the piece.
In this particular event I use a few expression pedals and a pedal looper instead of my own built Pure Data “effects” (I’d rather say processed signal).
