Question

Which of these is the distance from one letter note to the next instance of the same letter note?

tacet
ledger line
interval
octave

Answer 1

B. interval

Step-by-step explanation:

B is most likely the correct answer, since the others don't make sense:

A: Octave

Octaves consist of the interval of 8 notes. Like from C ~ C (8 notes), D ~ D (8 notes) etc.

C: Tacet

This doesn't support the meaning of "distance from one letter note to the next instance of the same letter note".

D: Leger Line

Leger line is a line that is consistently added during music writing. Usually, the bass/treble clef consists of 5 lines (four spaces). If music writers wanted additional space to write higher notes, they would add leger lines. This concludes that this option is not correct.

After eliminating the 3 options, we are left with B. Interval.

Therefore, the correct answer is INTERVAL.

Hope this helps! Feel free to comment with corrections/suggestions to improve this explanation. Thx! Have the most exciting day!

Answer 2

Octave

Step-by-step explanation:

A tacet (as of direction) is the voice or instrument silent.

A ledger line is used in Western musical notation to notate pitches above or below the lines and spaces of the regular musical staff.

An interval is a difference in pitch between two sounds.

An octave is an interval whose higher note has a sound-wave frequency of vibration twice that of its lower note.
