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.
Look at the number of keys on the keyboard. Digital keyboards can have as few as 25 keys or as many as 88. Digital pianos have the full 88 keys of a standard piano keyboard, and most workstations have at least 61 keys or more. Lower-end synthesizers may have as few as 25 keys, although most home-use keyboards come with 49, 61, or 76 keys. The more keys, the greater the instrument's range.
