Key Signatures Infographic for Vocal Music Education

Music theory infographic titled "Key Signatures: Sharps and Flats". STANDARD NOTATION KEY archetype, adapted as a vocal music education poster for voice / singing. Editorial sketchnote style, dark mode palette, chalk-like hand-drawn lines on a deep charcoal background with high-contrast white staff lines and accent colors in cool blue, muted gold, and soft red. Render musically accurate standard notation precisely: grand staff not required, use clear single staves with treble clef examples, key signature accidentals placed in correct staff positions, and organized comparison panels for sharp keys and flat keys. Show the order of sharps as F#, C#, G#, D#, A#, E#, B# and the order of flats as Bb, Eb, Ab, Db, Gb, Cb, Fb, each displayed as progressive key signature examples from 1 to 7 accidentals. Include concise English captions explaining how to read key signatures, how sharp keys and flat keys are identified, and a small visual guide for finding the major key from the last sharp or the second-to-last flat. Add a vocal-learning angle with a simple singer silhouette, breath marks, and pitch-reference noteheads near the staff, but do not include lyrics or copyrighted sheet music. Since the requested archetype is rhythm / time signature chart but the topic is key signatures, incorporate a small secondary sketchnote sidebar clarifying the difference between key signatures and time signatures, with a few simple time signature symbols only as contrast, not the main focus. Ensure notation is accurate; no finger positions unless naturally omitted for voice, and no irrelevant interval diagrams. Use clean visual hierarchy, hand-drawn arrows, boxed notes, legend callouts, and balanced infographic layout. Avoid any reference to the search-intent phrase and do not render it anywhere in the image. All text MUST be written in English (array). Every heading, label, caption, legend and metric name in the image must be in English — not English. Spell each English word correctly using English characters and diacritics. Numbers stay as digits, no watermarks Musically accurate notation, finger positions and intervals. Note names and Italian musical terms stay in canonical international form. No copyrighted song lyrics or sheet music.
