Some people tune their pianos monthly.
Some never tune them at all. It is probably reasonable to expect that, on average, pianos get tuned once a year.
But you don't really know that for sure.
Let's begin:
NYC Population: 3e6 people, more or less
Average size of household: 1.46 people / household
Average number of households having a piano: 11.7 households / piano
Number of pianos tuned by one tuner per day: 4 pianos (exactly)
Number of tuner workdays per year: 253 days (exactly)
Number of people per piano: 1.46 * 11.7 = 17 people / piano
Number of pianos per NYC: 3e6 / 17 = 176470 pianos / NYC
Number of pianos tuned by one tuner per year: 4 * 253 = 1012 pianos
Number of tuners needed to tune all the pianos in NYC: 176470 / 1012 = 174.
ANSWER: 174 tuners, more or less.
Note: A standard piano keyboard has 88 keys. An octave spans 12 keys, not 8. The number of keys is irrelevant, as is the number of strings, because a piano tuner will tune all the strings for all the keys when he/she tunes the piano.

How many piano tuners in the world?
The answer to the question depends on the definition of piano tuner. If you assume the question refers to professional piano tuners only, and includes those professional piano tuners who are not exclusively piano tuners, the number could be approximated as follows:Number of piano tuners in the world = (number of pianos that are periodically tuned in the world / average number of years between tunes for a periodically tuned piano) / average number of pianos tuned per year by piano tuners.Now:The number of pianos in the world = (the population of the world / number of people per household) * the number of pianos per household.The number of periodically tuned pianos in the world = the number of pianos in the world * the percentage of pianos that are periodically tuned.Where:The population of the world = 7,000,000,000Number of people per household = 5.5Number of pianos per household = 0.02Percentage of pianos that are periodically tuned = 40%Average number of years between tunes for a periodically tuned piano = 5Average number of pianos tuned per year by piano tuners = 100Number of piano tuners in the world = (7,000,000,000 / 5.5 * 0.02 * 40%) / 5 / 100 = 20,364Now, give me a job at google.com
