Decorative Duct Tape Piano Keyboard



Introduction: Decorative Duct Tape Piano Keyboard

Duct tape is the perfect starting point for making a decorative piano keyboard. Apply white duct tape (for the white keys) to a black surface. The black keys are shaped by partly cutting-away duct tape strips. Measures of the exact positions of the keys have been recorded and documented (see next step) to achieve maximum resemblance with a piano keyboard. In this Instructable the black surface of a cargo bike was turned into a decorative musical keyboard.

Besides its decorative purpose, the resulting piano keyboard may also be useful for practicing piano keys.

Step 1: Measures From a Piano Keyboard

The calculation spreadsheet introduced here is a tool to determine scaled variants for the key-layout of a musical keyboard. It contains measures in [mm] of the piano key layout (fixed base parameters). Based on the desired width (an input parameter in [mm], for example equaling a band of duct tape) a scaling factor is calculated, which is applied to yield the measures of piano keys exactly matching your duct tape width (the resulting output measures are reported in [mm] and [in]).

The spreadsheet is defined as an Open Document Spreadsheet (.ods) which is a modern open standard file type, to be opened and edited in any spreadsheet software.

The next step gives a few hints on the actual making of the decorative musical keyboard.

Step 2: Making

Some hints on the actual making of the decorative piano keyboard:

  • Preferably use cloth-backed duct tape because it doesn't shine through;
  • Cutting the notches (the cut-away black keys) can be done with a pair of scissors;
  • The point where the black keys end (at the crosswise cut) is an important reference for aligning the keys. The start and the end of the white keys may be best aligned using a final cut after all keys are in the correct position;
  • Lengthwise cutting the duct tape requires some skills. Remain patient and prepare mentally to start all over again (and remember: practice makes perfect).
