Create an educational and artistic image illustrating the concept of "tonal ratio" in music. The image should feature a musical staff with notes and clefs, emphasizing the relationships between different musical intervals and pitches. Include visual representations of intervals like octaves, fifths, and thirds, using lines or arrows to show their ratios. Add a circle of fifths diagram in the background to enhance the musical theory theme. Use subtle, harmonious colors to give the image a scholarly yet engaging feel. The overall design should convey the mathematical and auditory relationships that define tonal ratios in music.
