Field Notes: Voicing Oakville's Lakeshore Grands

Field Notes is a series about what we actually see tuning pianos across the GTA — one area, one pattern at a time.

In most of the GTA, a tuning visit is about pitch. In Old Oakville, Morrison, Eastlake, and Bronte — where the living rooms hold Steinways, Yamaha and Kawai grands, and the better European names — the conversation is as often about tone: "It's in tune, but it's gotten hard." "The treble is glassy." "It used to sound warmer." That's voicing territory, the most personal work a technician does, and the owners of fine instruments here have taught us most of what we know about explaining it. Here's what voicing is, how a session goes, and how to think about the bright-versus-warm question.

What voicing is

The tone of a piano lives in its hammers — wool felt, dense at the core and springier toward the surface, that strikes the strings. Fresh, resilient felt produces a rounded tone with a soft attack; felt that's been compacted by years of strikes (and cut with string grooves) produces a hard, bright, sometimes clangy tone with a lot of attack and little bloom. Voicing is the adjustment of that felt: reshaping grooved hammers back to a proper profile, then needling the felt to restore resilience where it's packed — or, less often, hardening felt that's gone too soft. Note by note, listening. (Harsh, tinny, or dull — the symptom-side guide.)

How a voicing session goes

1. Listening first. We play the piano through its range — soft, loud, single notes, chords — and hear where it's uneven: a bright band in the upper treble, a few notes that bark, a dull patch in the tenor. The owner tells us what they hear and what they want; that shapes everything.
2. Reshaping. Grooved hammers are filed to restore their rounded striking surface. This alone often removes much of the glassiness.
3. Needling. With fine needles, the felt is worked at specific depths and positions to soften and even the tone — a little at a time, testing constantly. Over-voicing can't be undone quickly, so it's deliberately gradual.
4. Evenness across the keyboard. The goal isn't just warm or bright — it's consistent from note to note so that a melody doesn't lurch.
5. A return listen a few weeks later, because voicing settles as the hammers seat, and fine adjustments then finish the work.

A meaningful voicing runs a couple of hours on a grand; a full reshaping-and-voicing longer. It's quoted after the listening step, and it's never rushed as an add-on to a tuning.

The bright-versus-warm question

There's no correct answer, only a correct answer for this piano in this room for this player. A few honest observations from Oakville's living rooms:

• Rooms matter as much as hammers. A grand on hardwood facing a wall of lake-view glass is bright before the hammers are touched. Rugs, curtains, a lid position — sometimes the room is half the voicing.
• Warm isn't the same as dull. A well-voiced warm piano still has clarity and sustain; it just has less attack. Owners asking for "warmer" usually mean "less harsh," not "less clear."
• Performers want more edge than listeners. A pianist practising repertoire for a hall may prefer a shade brighter than a household that mostly listens. Ask who plays most.
• Voicing follows tuning. Tone can't be judged on a piano with sour unisons; we tune first, always.

How often a fine grand needs voicing

Less often than tuning, more often than owners expect: a lightly played grand may want attention every five to eight years; a seriously played one every two to four, with small touch-ups at tunings in between. Bass-string dullness on an older grand is a different matter — that's the strings, and restringing the bass is the fix.

The lakeshore's humidity swings play a part too: felt softens in damp summers and firms in dry winters, so the same piano can sound warmer in August than in January. Steady room humidity keeps the voicing where it was left.

The relationship

Voicing is where a technician and an owner develop a shared vocabulary over years — "a little less bite in the top octave," "the tenor's gone woolly again." It's the most rewarding work we do on the most rewarding instruments, and Oakville's lakeshore has more of them than anywhere else on our route.

Common questions

What does voicing a piano mean?
Adjusting the hammer felt — reshaping worn hammers and needling or hardening the felt — to change and even out the piano's tone. It's separate from tuning (pitch) and regulation (touch).

How often should a grand piano be voiced?
Every five to eight years for a lightly played grand; every two to four for a seriously played one, with small touch-ups at tunings. Steady humidity keeps voicing stable between sessions.

Can a piano be made less bright?
Yes — reshaping grooved hammers and needling the felt softens the attack and restores warmth, while room changes (rug, curtains, lid position) handle the part that was the room, not the piano.
