where describes the instantaneous score of the note in given the semantic parameter and is applied to each parameter to describe its weight within the overall score. The transition score is described as

where is the score describing how well the transition between notes in the states and represent the transition between and . The optimal path is computed given these emission and transition scores for the semantic parameters.

4.5.3 Musical Results

The system is used to generate music under different conditions. The objective is to demonstrate that alternative musical decisions are made as a result of the physical constraints. Figure 4.18 shows musical outputs in which the semantic observation sequences are static, but the physical constraints are modified (see video for audio examples1). Thus, the differences among the outputs are a result of physical design and unique embodiment.

Fig. 4.18Embodied generation samples. Three motifs are generated to satisfy the musical parameters on the left using different physical constraints. 1. A single arm robot that can move at a fast rate of one half step per millisecond. 2. Robot with four larger and slower arms (Shimon-like setting) that must avoid collision. 3. Very slow moving single arm robot with a fast strike rate of 20 Hz
