What to wear? This is a fun­da­mental ques­tion of piano-tuning. As a piano tuner you will be in other people’s beau­ti­ful homes, walk­ing across their white car­pets, work­ing in their immacu­late liv­ing rooms or stud­ies. They expect you to be smart, but, on occa­sion, you need to rum­mage about in the filthi­est of instru­ments to extract broken parts and repair them. You can either turn the dirty jobs down, take an over­all, or keep a large ward­robe of smart but old clothes.

Your first appoint­ment is at nine o’clock. (This leis­urely start gives you a chance to answer emails and tele­phone mes­sages from the pre­vi­ous even­ing.) As you enter the hall of an eleg­ant town­house, the smell of fresh cof­fee greets you. The good news doesn’t end there. The cli­ent has just bought a fif­teen year-old Yamaha upright piano: a fine instru­ment in good con­di­tion. You have been highly recom­men­ded by their piano teacher so you do not have to prove your­self. Cli­ents who have not owned instru­ments before will stand around the piano and watch you work. They will ask how you became a piano tuner, when pianos were inven­ted, and how they work. This is a great oppor­tun­ity to show off and a won­der­ful anti­dote to the highly skilled but some­what lonely tun­ing pro­cess. So, allow plenty of time.

Next stop: a con­ver­ted barn a few miles out of town. You have to walk past a four-wheel drive BMW and a top of the range Mer­cedes to reach the door. As before, a new cli­ent, but this piano that has been bought on Ebay for fifty pounds. On first inspec­tion you reel off a well-rehearsed list of con­di­tions and pro­visos: ‘When we spoke price on the phone you didn’t say there were six broken ham­mer shanks. Do you real­ise that if I repair these, the oth­ers (clearly in a fra­gile state) will prob­ably break too? Because it is so far out of tune it may take a couple of ses­sions to get it up to pitch,’ and so on. The status of the piano tuner swiftly goes from one that is up with the GP or fam­ily account­ant, right down to gen­eral dogs­body who earns money for old rope, and whose visit is an unwel­come irrit­a­tion that has to be slot­ted in between get­ting chil­dren to rid­ing les­sons and shop­ping at Waitrose.

Because you did so much extra work on the Ebay piano, you eat your lunch as you drive to the local jazz venue. The band want the Stein­way tuned before they rehearse in the after­noon — and for you to call back before the gig in the even­ing to check and tidy. You work in the half light as road­ies clat­ter about with mike-stands and lad­ders, but you’ve tuned it a thou­sand times before and it is second nature, almost.

In the after­noon you visit an old cli­ent, a retired GP for whom you tune twice a year, as reg­u­lar as clock­work. He is par­tic­u­lar, and wants to dis­cuss any tiny prob­lem with the piano. But when you finally iron out any niggles, he is extremely appre­ci­at­ive and you leave feel­ing highly val­ued. Many tun­ings are on pianos for chil­dren learn­ing, but amongst adult musi­cians, Doc­tors, Uni­ver­sity lec­tur­ers and school teach­ers seem to rank high in number.

You head home to tele­phone mes­sages and emails. Piano tuners do not earn enough to employ sec­ret­ar­ies and the admin­is­trat­ive side of busi­ness stretches into the even­ing — an intru­sion that has been eased to an extent by the mobile phone and com­puter. Usu­ally, your work­ing day ends here as you settle in for din­ner with the fam­ily. But don’t for­get, you must return to check the Stein­way for the jazz.

The stage is cramped and you have to untangle the vocal mike-lead and the stage-light from the music desk before you can check the tun­ing. It has barely shif­ted. They could have man­aged without the extra visit, but you can always make some improve­ment. You spend ten minutes on the top octave. Money for old rope, you won­der? No, money for peace of mind; peace of mind for the pian­ist who can feel con­fid­ent that the piano will not reflect badly on her play­ing. And for you, know­ing that if the pian­ist is happy, you will be asked again.
