MULIPHEIN (Gamma Canis Majoris). The names Wezen and Hadar (in Arabic form) were once applied to a pair of stars. Though there are candidates, no one knows which pair. The uncertainty was in older times expressed as an Arabic word that in part referred to a pair of things that caused contention. The word itself was then taken as the pair, much mangled to Muliphein (sometimes seen as Muliphen), and then for no good reason given to the little star that Bayer later tagged as Gamma of Canis Major (while Wezen was given to our modern Delta, and Hadar to modern Beta Centauri).
- Piano (Wikipedia)
The piano is a keyboard instrument that produces sound when pressed on the keys. Most modern pianos have a row of 88 black and white keys: 52 white keys for the notes of the C major scale (C, D, E, F, G, A, and B) and 36 shorter black keys raised above the white keys and set further back, for sharps and flats. This means that the piano can play 88 different pitches (or “notes”), spanning a range of a bit over seven octaves. The black keys are for the “accidentals” (F♯/G♭, G♯/A♭, A♯/B♭, C♯/D♭, and D♯/E♭), which are needed to play in all twelve keys.
