You Will Need

  • A blade of grass
  • Two thumbs
  • Patience


  1. Step 1

    Pick a blade of grass

    Pick a flat blade of grass that’s as long as your thumbs.

  2. You’ll get more sound from wide, slightly coarse grass than from thin, fine grass.

  3. Step 2

    Put the grass between your thumbs

    Press your thumbs together at the knuckles with your fingernails facing you. Put the grass lengthwise between your thumbs.

  4. Step 3

    Pull the grass taut

    Pull the grass taut, so there are no kinks. You should see the edge of the blade centered in a gap between the base of your thumbs and your knuckles.

  5. Step 4


    Purse your lips, put your mouth to your thumbs, and blow. You may have to move your lips or thumbs slightly to make a sound, so keep trying.

  6. By cupping your hands, you can make the pitch of your whistle higher or lower.

  7. Step 5

    Experiment with sounds

    Play around with different kinds of grasses and reeds. You can make as many different sounds as there are blades of grass on your lawn.

  8. A grass whistle isn’t technically a whistle; it’s a reed instrument.
