The sentence I hear too often

"I'd love to learn piano, but I rent." I hear this constantly in Hamburg, and it is nearly always a solvable problem being treated as an impossible one. I teach students in Eimsbüttel flats with floorboards and walls from 1905. It works. But it only works if you understand what the neighbours are actually hearing.

Airborne and structure-borne sound

Almost all advice on this subject addresses only half the problem. Airborne sound is what you mean when you say "volume". The tone travels through air, hits the wall, and some of it arrives next door. Headphones, closed doors, rugs and curtains all help against it. Structure-borne sound is something else. It occurs when vibration passes directly into the building — from the instrument into the floor, from the floor into the ceiling, from the ceiling into the flat below. Structure-borne sound does not care about your rug, because it never travels through the air at all. And here is the part almost nobody knows: a digital piano with headphones still produces structure-borne sound. Not from the tone — that is inside your head — but mechanically. Eighty-eight weighted keys hitting their stops are a knocking. Through a wooden stand on a floorboard floor, that becomes a quiet, regular drumming in the flat below. I had a student whose neighbour complained even though she only ever practised with headphones. She was convinced he was imagining it. He was not. He was hearing her keybed.

What actually helps

Headphones. This is the big lever, and it eliminates airborne sound entirely. A digital piano with headphones is acoustically nonexistent to the neighbours. Use closed-back headphones — open ones radiate audibly, and you will be wearing them at night in a quiet flat. Decouple the instrument. This is what solves the drumming. Do not stand the piano directly on bare floorboards. Felt pads under the stand's feet are the first step; considerably more effective is a heavy board on resilient pads — even a yoga mat or a thick offcut of carpet under the whole stand makes an audible difference. The goal is to stop vibration travelling straight into the floor. Choose the right wall. Not the wall shared with a neighbour. An exterior wall is almost always best, an interior wall facing your own hallway second best. This sounds obvious and is still constantly got wrong, because the piano goes where it looks right. Work on touch, not force. This is the advice only a teacher gives: someone who can play quietly disturbs less. Control over touch is what we are working on anyway — here it just has a practical side effect.

What does nothing

Egg cartons on the wall. Acoustic foam. Both are designed for room acoustics — how it sounds inside your own room — and do essentially nothing for sound insulation to the flat next door. It is a very common and quite expensive misunderstanding.

Consideration beats rules

Most German house rules set quiet hours, usually overnight and often at midday as well. There are statutory and local rules on top of that, and German courts have repeatedly ruled on how many hours a day you may practise — so your Hausordnung and tenancy agreement are a starting point, not the whole answer. Making music at home is generally allowed, just not without limits. I am a piano teacher, not a lawyer: if it becomes a real dispute, ask someone qualified, such as a tenants' association. From experience, though: the single most effective step is a conversation before the instrument arrives. Tell your immediate neighbours, name the hours you intend to practise, and mention that you will mostly be on headphones. Almost every conflict I have seen a student run into was caused not by volume but by surprise.

If it has to be an acoustic piano

Some people eventually want a real instrument, and in a rented flat that is not a contradiction. Two designs exist for exactly this: Silent systems. An ordinary acoustic piano with a stop rail: you engage a lever, the hammers are caught just short of the strings, and the note is picked up by sensors and sent to your headphones instead. The action stays the real one — you are still playing a real piano. Yamaha builds this into its B series, other makers have their own systems, and many existing instruments can be retrofitted. TransAcoustic. The same idea taken a step further: the instrument uses its own soundboard as the speaker, so the digital tone comes out of the wood rather than a box. You can control the volume without losing the character. Both cost considerably more than a digital piano, and both are purchases for people who already know they are staying with it. You do not need either to start — but it is worth knowing that "rented flat" does not permanently mean "no acoustic piano". I do not list these instruments, because they need to be played before buying; Hamburg has good specialist shops for that.

What I recommend for small flats

For the overwhelming majority of my students in rented flats, a digital piano is the right answer — not as a compromise, but because it solves the problem cleanly. The AdYamaha P-45 ↗ is compact, light, and has a headphone socket. If two pairs need to go into it during a lesson, a simple headphone splitter costs a few euros — then I can listen in without the room getting loud. With more space and a little more budget, the AdRoland FP-30X ↗ serves better. The action is finer, and on the occasions you do play without headphones it sounds grown-up in the room rather than thin. Current prices are on my recommended instruments page. What to look for in the action — and why I consider it more important than the sound — is in why I insist on hammer action. If you are right at the beginning, start with your first piano instead.

Practising when there must be silence

There are evenings when even headphones are not an option, because a child is asleep next door. Something is still possible: work through fingerings on the tabletop, read the score and hear it internally, measure out difficult leaps silently on the keys. It is not a substitute, but it is not nothing either — movement patterns and score reading both measurably benefit.

If you are unsure

Describe your situation to me — floor, flooring, neighbours, budget — and I will tell you what I would set up in your place. In most Hamburg flats the answer is simpler than people expect.
