  • Technical specs: 

    3 Flutes (Flute I doubling piccolo, Flute II doubling alto flute, Flute
    III doubling bass flute)
    3 Clarinets in Bb

    Percussion I
    *2 cups or similarly small ceramic vases/pots
    (which produce noise with a hint of pitch when scraped, with bottom up,
    on top of a rough surface/sandpaper.)
    **Rough surface/sandpaper – circa. 30 cm x 30 cm (or wide enough to
    fit two cups/vases at the same time)
    ***/****Bongo drum (high and low) – with rough surface to be able to
    make aeolian sound
    ***/****Tom-Tom (high and low) – with rough surface to be able to make
    aeolian sound
    ***/****Gran cassa - with rough surface to be able to make aeolian sound

    Percussion II
    *2 cups or similarly small ceramic vases/pots
    (which produce noise with a hint of pitch when scraped, with bottom up,
    on top of a rough surface/sandpaper)
    **Rough surface/sandpaper – circa. 30 cm x 30 cm (or wide enough to
    fit two cups/vases/pots at the same time)
    ***/****Bongo drum (high and low) – with rough surface to be able to
    make aeolian sound
    ***/****Tom-Tom (high and low) – with rough surface to be able to make
    aeolian sound
    ***/****Gran cassa - with rough surface to be able to make aeolian sound

    Percussion III
    *2 cups or similarly small ceramic vases/pots
    (which produce noise with a hint of pitch when scraped, with bottom up,
    on top of a rough surface/sandpaper)
    **Rough surface/sandpaper – circa. 30 cm x 30 cm (or wide enough to
    fit two cups/vases/pots at the same time)
    ***/****Bongo drum (high and low) – with rough surface to be able to
    make aeolian sound
    ***/****Tom-Tom (high and low) – with rough surface to be able to make
    aeolian sound
    ***/****Gran cassa - with rough surface to be able to make aeolian sound

    Percussion IV
    *2 cups or similarly small ceramic vases/pots
    (which produce noise with a hint of pitch when scraped, with bottom up,
    on top of a rough surface/sandpaper)
    **Rough surface/sandpaper – circa. 30 cm x 30 cm (or wide enough to
    fit two cups/vases/pots at the same time)
    ***/****Bongo drum (high and low) – with rough surface to be able to
    make aeolian sound
    ***/****Tom-Tom (high and low) – with rough surface to be able to make
    aeolian sound
    ***/****Gran cassa - with rough surface to be able to make aeolian sound

    *There are 8 cups/ceramic vases in total and they should be in various
    sizes and shapes making 8 different pitches
    when scraped, with bottom up, on a rough surface. The cups/ceramic
    vases/pots should be divided between the percussionist so they form a
    scale of pitches, where percussionist I has the two highest pitches and
    perc IV the two lowest pitches
    and perc. II and III others in-between.
    ** This rough surface should not act as a resonator. The cups and vases
    are suppose to be their own resonators.
    ***Damped sound – drum with short resonance as of 1 second or so.
    ****If the drum skins have flat surface, it is possible to put tape with
    a rough surface on top of the skin.
