What this dot point is asking
Tone is the formal element that gives drawings and paintings their sense of form and light. Edexcel asks you to communicate through the formal elements, and tone is often the single biggest factor in whether a study looks convincing. This page covers the tonal range, how tone describes form and light, tonal contrast and key, and the techniques for building tone in your coursework.
The tonal range
The most common tonal weakness is staying in the middle. Strong tonal work uses the whole scale.
How tone describes form and light
Tone is the formal element that turns a flat shape into a believable form by showing where the light falls.
Tonal contrast and key
How much you jump between light and dark, and where your tones sit overall, are deliberate choices that affect drama and mood.
Techniques for building tone
Different techniques suit different surfaces, and using a range is AO2 evidence.
Why tone is the engine of realistic work
It is tempting to chase detail before tone, but tone does most of the work of making a study convincing, so it underpins your AO3 recording across the project. A drawing with accurate proportions but weak, mid-grey tone looks flat, while a looser drawing with a full, well-observed tonal range reads as solid and lit. The discipline of squinting to simplify a subject into a few tonal bands is the most useful single habit in observational work, because it stops you copying confusing detail and makes you see the big shapes of light and shadow first. Controlling tone is also AO2 refinement (choosing blending for one surface and hatching for another) and AO4 visual language (using contrast and key to carry mood). Many artists are studied chiefly for tone: Caravaggio and Rembrandt for dramatic chiaroscuro, Georges Seurat for soft tonal drawings in conte crayon, and Henry Moore for tonal shading that gives his figures sculptural weight. Analysing how they handle light gives you techniques to test and annotate, turning artist research into a tonal experiment of your own.

Q1. Name the tones you see on a rounded form lit from one side. [Knowledge recall]
- Cue. Highlight, mid-tone, core shadow, reflected light and cast shadow.
Q2. Explain why squinting helps you draw tone accurately. [Short explanation]
- Cue. Squinting blurs out confusing detail and reduces the subject to a few simple tonal bands, so you can see and place the big shapes of light and shadow correctly before adding detail.

Edexcel 1AD0 portfolio10 marksA candidate's drawings stay in the mid-greys and look flat. Analyse how using the full tonal range and stronger contrast would strengthen the work, and explain which assessment objectives benefit.Show worked answer →
An analysis needs the change, its effect, and the AO link.
The problem. Drawings restricted to mid-greys lack a full tonal range, so forms look flat and the light is unconvincing.
Using the full range. Pushing the darkest darks to near black and keeping the lightest lights clean (often paper white) describes how light falls, so a sphere reads as round. Squinting to reduce the subject to three or four tonal bands is the practical method.
Stronger contrast. High tonal contrast (chiaroscuro) makes form read powerfully and can add drama; placing the lightest light next to the darkest dark draws the eye to the focal point.
AO link. A fuller tonal range is direct AO3 recording evidence, and the deliberate control of contrast and technique is AO2 (refining media).
Markers reward the link from tonal range to form and a correct mapping to AO2 and AO3.
Edexcel 1AD0 portfolio6 marksExplain the difference between high-key and low-key tonal work, and the mood each can create.Show worked answer →
A short explanation needs both terms and their effects.
High key. Work dominated by light tones with little deep shadow. It tends to feel light, airy, calm or delicate.
Low key. Work dominated by dark tones with small areas of light. It tends to feel dramatic, sombre, mysterious or tense.
Why it matters. Choosing a tonal key is a way to control mood, which is part of using visual language for AO4. The same subject reads very differently in high and low key.
Markers reward both definitions and a sensible link from tonal key to mood.
