I'm looking for a melody on Musipedia but only know its general shape (whether the tune goes up, down, or stays the same). Describe how to use the 'Melodic Contour Search' method. Specifically, explain what 'Parsons Code' is, how it's used for input, and what kind of information it captures about a melody.
Navigate to musipedia.org. Locate and click on the 'Contour Search' link. Identify the description of 'Parsons Code' on the page. Explain how Parsons Code is used to input a melody for the 'Melodic Contour Search'. Describe what kind of melodic information Parsons Code captures (e.g., pitch changes, not exact intervals).
The agent successfully navigates to the 'Contour Search' page. The agent accurately defines Parsons Code as a rough description of the melodic contour. The agent explains that Parsons Code uses symbols (e.g., 'u' for up, 'd' for down, 'r' for repeat/same) to represent pitch changes. The agent states that Parsons Code captures whether the tune goes up, down, or if the pitch stays the same, without needing exact intervals.
