Final Answer:
I cannot provide a specific response to this assignment without the given bass and figures information for the triads and the specified key.
Explanation:
The assignment requires specific details, such as the bass note, figures, and key, to accurately identify and notate triads on the treble-clef staff. Without this information, it is not possible to provide a meaningful response.
The task involves understanding the figured bass notation, determining the appropriate triad, and notating it on the staff with the correct Roman numeral representation, considering inversions when necessary.
For a comprehensive solution, the bass note and figures associated with the triads, along with the key, are crucial. Once these details are provided, the process involves applying the principles of figured bass harmony to identify the triad, its position, quality, and inversion. Clear communication of these elements in the response ensures accurate completion of the assignment.
In summary, without the specific bass and figures information, it is not possible to address the assignment accurately. Providing the necessary details will enable a precise response in line with the requirements of identifying triads from figured bass notation.
