Mallet Foundations I · Lesson 1

Meet the keyboard family

Marimba, xylophone, vibraphone and bells look different and sound different. Under your hands, they share the same repeating map.

Four relatives, four voices

Marimba
Wooden bars, resonators and the broadest warm register in the family. Softer yarn or cord mallets are common.
Xylophone
Wooden bars with a shorter, brighter sound. Its written notes sound one octave higher.
Vibraphone
Metal bars, a sustain pedal and rotating fans. Its sound can ring after the mallet leaves the bar.
Bells
Small metal bars with the highest, brightest voice. Their written notes sound two octaves higher.

Same map, different range

Not every instrument begins and ends on the same note. The repeating order of the bars stays the same; each instrument shows a different-sized window into it.

Left is lower. Right is higher.

Stand at the player side of the instrument. Move left and the bars grow larger while the pitch moves lower. Move right and the bars grow smaller while the pitch moves higher.

From the player's position, pitch moves lower to the left and higher to the right. The bar sizes usually help you see the same direction.

“High” and “low” describe pitch, not where a bar sits vertically in the frame. An accidental bar may be physically farther away from you while sounding only one half step above the natural bar beside it.

Two rows, one keyboard

The long front-row bars are naturals. The shorter raised bars are accidentals. Some teachers call the two rows the lower and upper manuals.

Accidental bars repeat in groups of two and three. There is no accidental bar between E and F, or between B and C.

Do not count every bar from the bottom

Use the two-and-three pattern as a landmark. It works on every keyboard percussion instrument, even when the instrument begins on a different note.

C is left of two. F is left of three.

Find a group of two accidental bars. The natural bar immediately to its left is C. Find a group of three. The natural bar immediately to its left is F.

Every C and F is highlighted. C begins the two-bar pattern; F begins the three-bar pattern.
  1. Find a group of two accidentals.
  2. Move to the natural bar immediately left of the group. That is C.
  3. Find a group of three accidentals.
  4. Move to the natural bar immediately left of the group. That is F.

After B, the map starts again

The natural letter names run A B C D E F G. After G they repeat. From one C to the next C is an octave: the note name returns at a higher or lower register.

The same seven natural letter names repeat in every octave. Matching letters share a position inside the two-and-three pattern.

Once you can find C and F, every other natural is only a few steps away. That is the geography the next lessons will use for reading.

Open Mallet Board

The same topic, every way you need it

Hang it, read it, print it, drill it.

Every Backwerd topic identifies the faces that are ready — poster, lesson, printable sheet, app drill, board and teacher plans — and names an honest gap when one is not. The available faces share one set of conventions, so what hangs in the room never disagrees with what gets taught.
