8vb

8vb
Sidney Llyn 

The musical symbol 8vb (an abbreviation of ottava bassa, or “low octave”) is an indication to play notes an octave lower than written on the staff. 8vb eases the reading and writing of notes off the staff, which would otherwise have multiple ledger lines (see image).

8vb can affect a single note, or it may span several measures. In the latter case, it stops at the word loco, or at the end of its dotted, horizontal line.

If an entire staff is affected, a tiny 8 will be sitting atop the clef.

Also Written:

  • 8a b

Pronunciation:

Other Musical Abbreviations To Know:

  • Staccato

  • Marcato
    Informally referred to as simply an “accent,” a marcato makes a note slightly more pronounced than surrounding notes.
  • Sforzando
    Makes a note considerably louder than surrounding notes. When a single note is affected, the abbreviation sfz is used.
  • Legato or Slur

  • Comparing Major & Minor
    Major and minor are often described in terms of feelings or mood. The ear tends to perceive major and minor as having contrasting personalities; a contrast that is most obvious when the two are played back to back. Learn more about major and minor scales and keys.

Enharmony:

  • The 6 Enharmonic Key Signatures
    If you’re familiar with the circle of fifths (or you just know your way around the key signatures) you may have noticed a few anomalies. Some keys – like B-sharp and F-flat major – are seemingly absent, while others go by two names
  • The Inefficient Keys
    The circle of fifths shows only the working scales. But, if we expand on its pattern, we can see that it’s actually more of an infinite spiral, so there’s no end to the possibilities of musical scales.
