Although employees may accrue more than three days of paid sick leave under the one hour for every 30 hours worked (or under an alternative accrual standard) under an accrual method, the law allows employers to limit an employeeâs use of paid sick leave to 24 hours or three days during a year.
Modern piano keyboards ordinarily have an octave span of 164â165 mm; resulting in the width of black keys averaging 13.7 mm and white keys about 23.5 mm wide at the base, disregarding space between keys. Several reduced-size standards have been proposed and marketed.
There's even a piano made today--the BÃ¶sendorfer Imperial Concert Grand--which has 96 keys; the bass notes go all the way down to C. It's nine-and-a-half feet long and weighs almost a ton. Q: How many strings does a piano have? A: It depends on the piano. Each note has three strings in the treble, two strings in the tenor and part of the bass, and only one in the very low bass. One of ours has 65 trebles (X 3=195), 12 tenor/bass (X 2=24), and 11 single low bass, so it comes out to 230. But that's a large grand, so you need to look in your piano and count them up.
