Understanding Musical Notes and Their Durations

In Western musical notation, notes are represented by the letters A, B, C, D, E, F, and G, corresponding to La, Si, Do, Re, Mi, Fa, and Sol. The piano keyboard features 12 notes: A, A#/B♭, B, C, C#/D♭, D, D#/E♭, E, F, F#/G♭, G, G#/A♭, repeating in octaves. A crotchet, or quarter note, represents one beat, while a semibreve, or whole note, lasts for four beats. A minim is worth half a semibreve and twice a crotchet. Other notes include the semiquaver, lasting half a quaver, and the demisemiquaver, lasting half a semiquaver.
