Trying to find a song

This is a high school level song I think it’s starts with the cellos and bass the cellos start on the g and c sting first finger and it’s div and then they play some notes before the cellos slide from 4th finger g or c to a 1st finger on g or c and then the violas like slap the front of their instruments to make like percussions I had the sheet music but I’ve lost it and I think it’s fairly new the title started with a b the beginning was \[whole note\] \[quarter note\] \[eight note\] \[quarter note\] \[quarter note\] \[dotted half note\] \[quarter note sliding to whole note\]
