Detail 01
5-note chromatic set
These are the black-key pitches only. Without a diatonic set alongside, you cannot play most melodies.

Independent shopping perspective
Five pitched plastic tubes covering the sharps and flats of the upper octave. Buy as an add-on to a diatonic Boomwhackers set, not on its own.

What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 01
These are the black-key pitches only. Without a diatonic set alongside, you cannot play most melodies.
Detail 02
Shorter tubes, higher pitch. They will not stack with a lower-octave chromatic set's range.
Detail 03
Each tube sounds a fixed pitch, so a group plays a melody by having each person hit on cue.
Detail 04
Pitch comes from tube length, not tension, so they never go out of tune and never need adjustment.
Detail 05
Cheap enough to replace individual tubes as they crack rather than repairing them.

Product questions
Straight answers to the questions shoppers most often ask about this product.
The five chromatic pitches, meaning the sharps and flats, in the upper octave. It fills the gaps in a diatonic set rather than standing alone.
Yes, for practical purposes. Five chromatic notes on their own cover almost no melodies. This is designed as an extension.
No. Pitch is set by the length of the tube, so it does not drift.
Strike the tube against a palm, thigh, or the floor. Harder surfaces are louder but wear the plastic out sooner.
