Peter Sculthorpe (now deceased) is an Australian composer well known for his infatuation with the sounds of Indonesian Gamelan music. In some of his compositions for orchestra he asked the basses to make raindrop sounds by hitting the strings with the bow stick (col legno battuto) between the bridge and the tailpiece, or bow a slur across the 4 strings in the same place with up or down bow, or bow across the tailpiece to give a very deep resonant sound,or twist a creaking sound by resting heavily on two lower strings. In this case you pivoted the bow on one string by pushing the frog towards the bridge on the other string with no sideways movement of the hair. In a piece called Ketjak we had to wear a boot and stamp our foot very loudly.
In his book, The Art of Bass Playing, Warren Benfield gave a list of nomeclature and symbols required for contemporary music of the times. I would recommend buying this book that contains so much wisdom.
Also in his piece, "Threnody for the Victims of Hiroshima", Penderecki asked for the wonderful sounds of tutti strings playing huge crescendos and diminuendos while player 1 stayed on the first note, player 2 moved apart glissando up or down a 1/4, tone, player 3 a 1/2 tone, player 4 a 3/4 tone, etc,etc, finishing or starting in huge blocks of dissonance. In between there were in-tune passages to play. It may be on You Tube.
All the best for Christmas,
