How to disinfect a piano

The Riddle of Piano Disinfection

We are next to starting a new stage in this pandemic: the prudent and conscious attempt to come back to this proposed "new normality".

Many educational organisations, primarily those capable of organizing "classroom-lessons", are thinking of restarting their activities within the frame of strict hygiene and precaution rules.

What is the situation with one-to-one instrumental or voice sessions?

Our set-up

A one-to-one piano lesson involves:

  1. A piano used both by the teacher and the student

  2. A student sat in front of the piano

  3. A teacher sat between 30 cm to 1 m from the student.

The piano

The piano is made of wood and ivory, in the case of old pianos.

New digital pianos are made of wood and plastic.

Wood is a porous surface, mainly present in the inner or hidden side of the keys.

Wood is a tough surface to clean.

According to:

The virus survives on wood for 4-days!
The virus survives on plastic for 3-days!

One millimetre gaps separate one key from the other. During the action, the inner side of the key surface comes in contact with the side of the student's fingers.

The keyboard of the piano offers a huge challenge during the pandemic:

Its proper disinfection.

How do we guarantee that the inner faces of the 89 keys of all our keyboards are properly disinfected? How do we treat the instrument without wetting it?

These are questions which remain unanswered at the current point of time.

The Interaction

The teacher needs to exemplify in the same piano the student plays using his or her hands.

The teacher and the student will talk in front of the instrument. The droplets will fall on the surface of the keys, and the sweat of the hands will be easily shared by:

  1. The teacher

  2. The current student

  3. Possibly the following and previous students.

The teacher will be tempted to check the tension of the student arm and hand by touching the student's hands.

The Cleaning

The sophisticated keyboard of a piano offers several different unreachable areas that will be left, almost inevitably, not-disinfected in between lessons.

The ideal distance between the teacher and the student

If we try to impose the ideal 2-metre distance between the teacher and the student, the result will be that the face-to-face lessons will become less explanatory that the online sessions.

At least, in the online lessons, the teacher is capable of showing via close-up any movement the student needs to use.


WKMT has taken the decision of staying closed for the time being for face-to-face lessons until we see the development of the pandemic once after the relief of measures take place.

We will continually reassess the situation throughout the coming months with the intention of opening in September or earlier.

However, our online piano lessons are perfectly designed for all those students who would like to continue with their musical education.

Our key concerns are:

  1. The health of our students

  2. The health of our teachers

  3. The health of our students' and teachers' families.

Our key expectations to reopen are:

  1. The creation of a vaccine

  2. The creation of a treatment

  3. The confirmed positive herd immunization

On the meantime, we will continue delivering online piano lessons which offer the same facilities as the face-to-face lessons. So far, 90% of our current students are doing so.

What's the primary reason for supporting our decision?

"The inefficient and unreliable cleaning options available to approach the disinfection of piano keyboards to the standards needed to guarantee 0 infections.

Difficult area: Inner hidden sides of the keys regardless of being plastic or wooden."
