Consider the following statements: 1. A widely used musical scale called diatonic scale has seven frequencies. 2. The frequency of the note is 256 Hz and that of is 512 Hz. Which of the statements given above is/are correct?

Statement 1 is correct: the diatonic scale in Western music is a seven‑note (seven‑degree) scale, commonly represented by the sequence do–re–mi–fa–so–la–ti, often discussed as the seven natural pitches of a mode or major scale. Statement 2 is also correct in the sense that multiplying a note’s frequency by 2 raises it by one octave, so a tone at 256 Hz and the tone at 512 Hz are the same pitch class separated by one octave; thus 512 Hz is the octave above 256 Hz. Therefore both given statements are correct.
