The MIDI system for electronic musical instruments and computers uses a straight count starting with note 0 for C at 8.1758 Hz up to note 127 for G at 12,544 Hz. A written note can also have a note value, a code that determines the note's relative duration. In order of halving duration, they are: double note (breve); whole note (semibreve); half note (minim); quarter note (crotchet); eighth note (quaver); sixteenth note (semiquaver).;
Structured note Structured note A structured note is an over the counter derivative with hybrid security features which combine payoffs from multiple ordinary securities, typically a stock or bond plus a derivative. When it depends on a credit payoff, it is called a credit-linked note. A simple example of a structured note would be a five-year bond tied together with an option contract. The addition of the option contract changes the security's risk/return profile to make it more tailored to an investor's comfort zone. This makes it possible to invest in an asset class that would otherwise be considered too risky. From
