Note Value Chart Infographic with Circle of 4ths Chart Accent

Music theory infographic titled "Note Value Chart". Archetype: STANDARD NOTATION KEY. Editorial music education poster in sketchnote style, dark mode palette, designed for voice / singing. Render a precise grand staff with clear note-value progression shown musically accurately: whole note, half note, quarter note, eighth note, sixteenth note, including corresponding rests, beams, stems, flags, and measure-based duration relationships. Show a clean visual hierarchy with large central staff notation, proportional duration comparison, beat grouping, and simple singer-focused timing cues using neutral vocal pedagogy visuals, avoiding any instrument-specific fingering. Include a subtle hand-drawn classroom aesthetic, chalk-on-dark-paper look, high contrast white notation with muted accent colors. Add small supporting diagrams showing how notes subdivide across measures in common time, with barlines and count grouping presented as infographic elements. Include a secondary circular reference motif inspired by a circle of 4ths chart as a decorative visual search-intent cue only, but do not make it the main topic and do not include any non-relevant theory content.
