The pressure ramp and layering

Dialling tone like a volume knob, and why layers beat force

Produce a smooth pressure ramp and understand in the hand why value is built in layers.

Why this one

  • Unit 1 of the program: Instrument Control.

The plan

4 stages · ~41 min
  1. 1

    Ten ramps

    12 min

    2B on its side, overhand grip. A band an inch tall and eight inches long, starting with a touch so light it barely marks and ending with the full weight of the hand, with no steps. Count to eight as you travel and let the pressure rise with the count. Do ten. The tenth will be much better than the first.

  2. 2

    Reverse and compare grades

    12 min

    Five ramps dark to light. Then two ramps with the 6B: notice how little pressure the dark end needs. Then two with the 2H: notice that the dark end never arrives, however hard you press, and that the paper dents.

  3. 3

    The two greys

    12 min

    Make a two-inch square of middle grey by pressing hard with the 2H. Beside it, make the same grey with three light layers of 2B, changing direction between layers. Tilt the sheet to the lamp. The first shines. Now try to darken each one with a 4B: the pressed one refuses; the layered one takes it. You have just learned the most important rule in pencil drawing in your hand, not your head.

    Two swatches of the same middle value: one made by pressing hard with a hard pencil, which grooves and shines, and one made by light layers of a soft pencilWRONG · 2H, PRESSED HARDgrooves, shines, cannot go darkerRIGHT · 2B, THREE LAYERSmatte, keeps tooth, can go darkerRule: reach a value with a softer pencil and lighter touch, never a harderpencil and more force.Pressure is a one-way door.

    Self-check

    5 min

    Tick each item honestly. If one is a no, the session is not finished; go back to that step.

    Checklist0 / 3

What it should look like

  • A ramp with no visible steps.
  • Two grey squares, one shiny and dead, one matte and alive, with your note about which took more tone.

Where it goes wrong

  • Ramps with three or four distinct bands. Thinking of the pressure in stages. Count continuously and move faster; speed smooths pressure.
