Piano Technician Notes on iPhone: Tuning History, Regulation Records & Client Piano Service Notes

Piano service combines tuning, regulation, voicing, and repair across instruments that may be decades or centuries old. A Steinway concert grand that's been at 415 Hz for fifteen years requires a careful pitch raise sequence before it can hold standard pitch. A piano with poorly regulated action may need geometry measurements before any voicing makes sense. The piano technician who serves each instrument well does so by knowing its history — and Nemos is where that history lives.

Why Piano Technicians Need Structured Notes

Every piano has a service history that determines how to approach the next visit. A piano that's been recently regulated responds to voicing differently than one with worn parts. A pitch that's been slowly dropping for years may be more stable than one that was recently let go. Without documented service history, each visit starts fresh; with notes, the technician arrives knowing what was done, when, and with what result.

What to Capture in Nemos

Piano Identification and Baseline At first service visit: - Make, model, and serial number - Manufacture date (derived from serial number) - Action type and any rebuilding history evident - Soundboard condition (crown present, cracks) - Pinblock condition (visual assessment) - String condition (rust, false strings evident) - Pedal and action regulation condition - Room location and humidity environment

Baseline notes orient every subsequent visit without needing to re-examine from scratch.

Tuning Records At each tuning: - Date and pitch level found - Stability at pitch level (holding well, dropping, inconsistent) - Whether pitch raise was required - Tuning approach used (ETD, aural) - Final pitch stability assessment - Any strings noted as false

Tuning history tracks pitch stability trends — useful for scheduling advice and humidity system recommendations.

Regulation Assessment Notes When assessing or performing regulation: - Key dip and aftertouch measurements - Let-off and drop settings - Repetition spring tension - Damper lift and travel - Pedal lost motion and travel - Observations on wear (worn buckskin, weak hammer flanges, etc.)

Regulation notes document the baseline before adjustment and the target achieved — both useful for comparison at the next visit.

Voicing Observations After voicing work: - Initial tone character (thin, bright, hard, muffled) - Voicing approach taken (needling, lacquering, steaming) - Outcome assessment by register - Client or player feedback - Sections requiring further attention

Voicing notes are qualitative but consistent vocabulary makes them comparable across visits.

Humidity System Notes - Humidifier/dehumidifier type and location - Target humidity and current room humidity at service time - System condition (damper material, reservoir level) - Recommendation made to client - Seasonal notes on humidity variability in this room

Humidity notes explain much of the variation in tuning stability. Clients who follow humidity recommendations have better-maintaining pianos — documenting the connection helps.

Client Communication Notes After each visit: - Key findings communicated to client - Any work recommended but deferred - Next service timing recommendation - Client's expressed priorities

Communication notes prevent the "but you never told me" problem and build a trusting service relationship.

FAQ

Can I use Nemos offline on location in client homes? Yes. Full offline functionality — a requirement for any mobile service technician. Notes sync to iCloud when back on WiFi.

How do I organize notes across a large client roster? Use client last name or piano serial number as the primary note title. Tags by service type (tuning, regulation, repair) and piano brand keep the roster navigable.

Is Nemos useful for tracking concert piano prep work? Yes — especially for multi-session prep where regulation, voicing, and final tuning happen across separate visits. A running prep note captures each session's work and the target spec.

Can I attach photos of hammer condition or action geometry? Yes. Attach photos of worn hammers, broken parts, or damper condition. Visual documentation is especially useful for repair recommendations that clients need to approve.

How do I handle notes for multiple pianos at the same institution? Create a note per piano with its make/model/serial as the identifier. Tag by institution name for grouping. Finding all service notes for a school or concert hall is a single search.

Why not just rely on visit memory and experience? Experience tells you what to look for. Notes tell you what was found — and what changed since the last time.
