There are two things to observe in this video. One is proper PIM Arpeggio technique happening in a piece of music. The other is the high degree of dynamic contrast (primarily in the form of crescendo) exhibited by the ensemble. Remember, our goal at all times is Expressive Music Making!
Bell and Pendulum is a level 6 piece from the curriculum. It is the quintessential classroom arpeggio study because it allows all parts of the ensemble to perform PIM arpeggios in a musical context. This is a great piece to help introduce PIM arpeggio to your ensemble. Note that Bell and Pendulum requires four parts in your ensemble.
Please see the Sequence Document attached to the score in the music library that provides detailed information on how to effectively introduce this piece to your students.
