Final answer:
The exact instruments and views on musicianship favored by Isa Maud Ilsen are not provided, but fundamentals such as rhythm, melody, timbre, and the cultural significance of music could align with qualities valued in music therapy.
Step-by-step explanation:
Isa Maud Ilsen's preferred instruments or views on musicianship were not explicitly mentioned. However, understanding the concepts of rhythm and melody, timbre, and the importance of music might shed light on what qualities she might have valued in music therapy (MT).
Rhythm is the pattern of beats or a sequence of sounds in time, while melody refers to a succession of musical tones that are perceived as a single entity. A beat is the basic time unit in music, and rhythm is how these beats are organized. Timbre is the quality of a musical note or sound that distinguishes different types of sound production, such as instruments or voices. Instruments differ from each other in timbre due to their construction and the way they produce sound.
The perception of harmony versus dissonance, where some combinations of notes sound pleasant and others don't, is due to the frequency ratios between the notes. Music can be central to a culture and community, serving as a means of expression, communication, and unity. Music and arts are interrelated as they both engage the creative aspects of human culture, conveying emotions and ideas beyond words.
