tower of Babel Making sense out of chaos
Main content: glissandoA glissando is a musical term of Italian origin that designates the continuous sliding of a sound in an upward or downward movement. The glissando can be produced by the human voice and, among other things, by stringed instruments and the slide trombone. A glissando effect can be produced on fixed pitch instruments such as the piano and the harp...
Pedagogical objectives
- The student is able to create a smooth glissandoA glissando is a musical term of Italian origin that designates the continuous sliding of a sound in an upward or downward movement.

- The student is able to respond precisely to the gestures of the conductor
Pedagogical intentions
- Familiarize the student with the concepts of glissandoA glissando is a musical term of Italian origin that designates the continuous sliding of a sound in an upward or downward movement. The glissando can be produced by the human voice and, among other things, by stringed instruments and the slide trombone. A glissando effect can be produced on fixed pitch instruments such as the piano and the harp... and reverberation
- Improve the students response to the conductor’s gestures

Process
The teacher plays each of the “hello, bonjour, guten tag” files, asking the students to identify each language. The version corresponding to the mother-tongue of the students is played reversed (without warning), so as to introduce to the students, the reverse playback function.
Step by Step
- The teacher asks each student to select (with the selection-tool) one of the “hello” greetings: "sounds - varia" bank > [hello]. The student activates this sound when the conductor points to them.
- The teacher points to each and every student, until each sound is activated (tutti). Once tutti has been achieved, a moment is taken to appreciate the “Tower of Babel” effect (chaotic mixture of languages, phasing effect...).
- Following the gesture of the conductor, the student initiates a glissandoA glissando is a musical term of Italian origin that designates the continuous sliding of a sound in an upward or downward movement. The glissando can be produced by the human voice and, among other things, by stringed instruments and the slide trombone. A glissando effect can be produced on fixed pitch instruments such as the piano and the harp... by slowly sliding their sound into the extreme high register, using the pitch/speed tool.
- The teacher initiates another glissandoA glissando is a musical term of Italian origin that designates the continuous sliding of a sound in an upward or downward movement. The glissando can be produced by the human voice and, among other things, by stringed instruments and the slide trombone. A glissando effect can be produced on fixed pitch instruments such as the piano and the harp..., this time in the opposite direction: a glissandoA glissando is a musical term of Italian origin that designates the continuous sliding of a sound in an upward or downward movement. The glissando can be produced by the human voice and, among other things, by stringed instruments and the slide trombone. A glissando effect can be produced on fixed pitch instruments such as the piano and the harp... down to the lower register.
- The teacher can optionally add the reverberation effect.
- The teacher ends the experiment by either cutting all sounds suddenly or by initiating a slow decrescendo.
- Assessment: Were the crescendos and decrescendos well executed (smooth and following the gesture of the teacher/conductor)? Were the glissandos well executed (smooth and following the gesture of the teacher/conductor)? When using extreme variations of speed, can one still understand the words spoken? Which images and sensations come to the mind of the student during these extreme variations?
VARIATION: The group is divided into 7 sub-groups, each responsible for a different “hello” greeting, allowing interesting cross-fades and polyphony among/between the groups.
NOTE: The teacher can ask a student to conduct.
