Meisterprüfung Musikinstrumentenerzeuger · Understand the traps and how to avoid them.
Calculating a workshop offer price by adding material cost and an hourly wage for labour only, then presenting that figure as the final price, with no workshop overhead, machine-hour rate, risk or profit margin included.
Candidates learn costing from small repair jobs where the price is dominated by visible material and time; they confuse a self-employed person's wage with the full cost of running a workshop, and they have rarely built a real overhead recovery rate, so they under-price and lose marks on the calculation as well as on business judgement.
What to do instead
Before the exam, build a complete cost scheme for a sample instrument: direct material, direct labour at a fully loaded hourly rate, machine-hour rate, workshop overhead as a percentage surcharge, then risk and profit. In the exam, show every line of the scheme and state the surcharge percentages explicitly, so the marker can follow the arithmetic.
Quoting legal rules from memory as fixed numbers (notice periods, probation length, working-time limits, contribution rates) without checking whether the rule applies to the specific case, or mixing up the rules for minors with those for adults.
Legal topics are memorised as lists of numbers during preparation, and candidates reproduce them under time pressure without asking which statute, which contract type or which age group is at issue; the Jugend- und Auszubildendenschutzgesetz and the Arbeitszeitgesetz are easily confused because both regulate young workers.
What to do instead
Answer legal questions in a fixed order: name the relevant statute, state the rule, then apply it to the facts of the case. Where a number is uncertain, state the principle and mark the figure as approximate rather than inventing a precise value. Practise short cases involving a 16-year-old apprentice and an adult employee side by side.
Handing in a technical drawing that is dimensionally correct but lacks a title block, scale statement, material specification, tolerances, surface or finish notes, revision index and a parts list for a multi-component assembly.
Candidates treat drawing as a test of line work and geometry and see annotation as clerical decoration; in workshop practice they usually work from a drawing someone else has already annotated, so they never experience the consequences of missing information and do not internalise the documentation standard.
What to do instead
Adopt a checklist that is applied to every drawing before it leaves the bench: title block complete, scale stated, all materials to standard designation, general tolerances per the applicable ISO class, fits given as tolerance pairs, surface finish symbols, and a numbered parts list matching the assembly. Rehearse by drawing one complete small assembly, such as a bridge or a tuning-pin block, to full documentation standard.
Describing wood selection and seasoning only in general terms ('well-seasoned, straight-grained spruce') without naming the species, the cut, the moisture content target, the grain run-out or the defect criteria that decide the choice for a specific part such as a soundboard, a neck blank or a bass bar.
Much workshop knowledge is tacit and passed on by feel and by eye; candidates can recognise good stock in the rack but have no vocabulary for the measurable criteria, and exam questions that ask for a justification tempt a vague answer instead of a specification.
What to do instead
For each major component, prepare a one-page specification: species and botanical name, quarter-sawn or slab-cut, target moisture content with the equilibrium figure for the workshop, acceptable grain deviation in degrees or millimetres per metre, and rejection criteria such as compression wood, knots or spiral grain. Answer material questions by applying that specification to the named part.
Explaining acoustic behaviour with a single slogan ('thin top means more volume', 'hardwood gives a brighter tone') instead of separating the relevant physical quantities such as mass, stiffness, damping, air resonance and the coupling between the air cavity and the body.
Tone description in the trade is metaphorical and tradition-bound, and candidates repeat shop-floor sayings without linking them to measurable properties; they also lack practice in applying the basic relations of frequency, wavelength and vibration modes to a real instrument.
What to do instead
Practise explaining one instrument in physical terms: state how plate mass and stiffness affect the mode frequencies, how the Helmholtz-type air resonance of the body interacts with the top, and how damping changes sustain and attack. Where a claim is qualitative, say so and give the direction of the effect rather than an absolute statement.
When answering a restoration or valuation question, proposing to replace a damaged original part with new material, or refinishing an instrument, in order to make it look better, without first establishing the instrument's significance, originality and the effect of the intervention on its value.
Candidates transfer repair logic from routine maintenance, where making the instrument work and look good is the goal, into the treatment of historic objects where minimum intervention and reversibility govern; they also underestimate how strongly documented originality drives market value.
What to do instead
Answer restoration questions in a fixed sequence: document condition and originality, establish significance and the client's aim, then choose the least invasive option and state its reversibility, the materials used and what is recorded. For valuation, separate the value drivers (maker, provenance, condition, originality, rarity) and state explicitly how the proposed work would change each.
Advising a customer on an instrument or a repair without asking about playing level, repertoire, physical fit and budget, and without documenting the advice given and the customer's decision in the order paperwork.
Candidates focus on the technical problem in front of them and treat the conversation as a friendly chat; they have little experience of the liability and warranty consequences of informal advice, so they neither structure the consultation nor record it.
What to do instead
Use a short structured consultation routine: needs and playing context, options with advantages and limits, recommendation with reasons, cost and timeframe, then a written summary signed by the customer. In exam case questions, show the questions you would ask before recommending, and name the documentation you would produce.
Listing workshop hazards as a general sentence ('wood dust and machines are dangerous') instead of identifying the hazard at a named operation, the exposure route, the protective measure hierarchy and the required personal protective equipment for that task.
Safety content is often learned as a list of rules to be recited, and candidates have internalised safe habits so deeply that they cannot articulate them; they also confuse personal protective equipment with the more effective engineering controls.
What to do instead
For each core operation (sanding, sawing, chiselling, gluing, spraying, soldering, string under tension), write the hazard, the exposure route, the engineering and organisational controls first, and the PPE last. In the exam, answer by operation, and state the hierarchy explicitly so the marker sees that controls precede protective equipment.
Describing a hand-tool or machine operation as a sequence of steps without stating the reference surfaces, the order of material removal, the checking method and the permissible deviation at each stage.
Practical skill is performed rather than verbalised, so candidates narrate what they do with their hands but omit the measurement logic that makes the result reproducible; examiners cannot award marks for a procedure that never says how correctness is verified.
What to do instead
Write each procedure in four columns: reference surface, operation, measuring or checking method, and tolerance. Rehearse by writing out three core procedures (preparing a joint, fitting a bridge, setting up a fretboard) in this format and checking them against the drawing conventions you use in technical drawing.
Treating waste disposal, solvent and adhesive handling, and dust extraction as an afterthought in the costing and in the workshop layout, so that environmental compliance appears only as a closing sentence about 'disposing of waste properly'.
Environmental rules feel remote from instrument making and are learned late; candidates also separate environmental protection from occupational safety, although extraction, ventilation and disposal decisions are usually the same decision and carry real cost.
What to do instead
Integrate environment into every process description: name the waste stream, the collection and disposal route, the legal category where relevant, and the cost line in the calculation. When laying out a workshop or costing a job, show extraction, ventilation and disposal as planned items with their cost, not as a footnote.
