Octave Sign 8va and 8vb - Phamox Music (2024)

Octave Sign 8va and 8vb

Ever come across the octave sign 8va and 8vb in your music score and wonder what they mean?

You’re not alone! These markings are quite common in music. While music notation may seem complex at first, it’s actually a clear system that composers and musicians use to communicate.

This article will explore the world of octaves and vocal registers and explain the meaning behind 8va and 8vb.

By the end, you’ll be able to confidently read any piece of music that uses these symbols.

Unveiling the Octave Sign

The foundation of Western musical scales lies in the concept of the octave.

An octave refers to the interval encompassing eight notes, encompassing a specific range of pitch.

Imagine climbing eight keys on a piano, either white or black, consecutively.

The starting note and the eighth key you land on create an octave relationship.

This interval holds a special place in music theory because it represents the most acoustically pleasing doubling of a pitch.

The higher note essentially mirrors the fundamental frequency of the lower note at twice its speed, creating a sense of completeness and resolution.

Understanding octaves allows us to navigate the vast spectrum of pitches available in music.

Instruments like the piano possess a limited range of keys, but musicians can access a much broader range of notes by utilizing octaves.

By understanding octave relationships, musicians can transpose music to different keys or play melodies outside the instrument’s written range.

What Do Octave Signs 8va and 8vb Mean in Music?

The octave signs 8va and 8vb are musical notations that instruct the performer to play notes an octave higher or lower than written.

Here’s a breakdown of their distinctions:

8va (Ottava Alta)

This abbreviation stands for “ottava alta” or “ll’ottava,” which translates from Italian to “higher octave.”

When encountered on a sheet of music, 8va instructs the musician to play the notes in an octave higher than written.

It’s written above the notes and often has a dashed line showing how long the higher octave applies.

A dashed line typically extends above the notes affected to indicate the duration of the octave shift.

8va allows composers to write melodies for a specific instrument’s comfortable register while ensuring the intended pitch is conveyed.

NOTE

• When placed above a passage of music, it indicates that the notes should be played one octave higher than written.
• If you see a C written with an 8va above it, you will play the C one octave higher on the staff.
• The notation “8va” (or sometimes “8”) is specifically employed above a treble clef staff and should not be utilized above any other clef.
• Typically, this notation is accompanied by an extender line, which consists of a broken line with a downstroke at the end.
• When indicating an “8va,” it should be aligned centrally above the notehead.
• The end of the “8va” bracket extends to encompass the notes affected by the octave change.

8va or 8vb (Ottava Bassa)

The counterpart to 8va (Ottava Alta), 8vb (Ottava Bassa, “lower octave”), instructs the musician to play the notes involving an octave lower than written.

It’s written below the notes with a similar dashed line. Like 8va (Ottava Alta), a dashed line typically extends below the notes to denote the extent of the octave shift.

8va Bassa is particularly useful for instruments with limited lower registers, allowing composers to expand the tonal range without exceeding the instrument’s capabilities.

NOTE

• When the notation “8va” (or simply “8”) is positioned below the staff, particularly in keyboard music, it is universally interpreted as indicating “8va bassa.”
• The designation “8va bassa” is exclusively used below a bass clef staff and should not be employed with treble, alto, or tenor clefs.
• Typically, an extender line accompanies the 8va bassa notation, which consists of a broken line with an upstroke at the end.
• The start of the 8va bassa notation is placed beneath the notehead.
• Primarily, the end of the 8va bassa line extends slightly beyond the last affected note.
• If you see a G written with an 8vb below it, you will play the G one octave lower on the staff.
• Less commonly used than 8va, it can also be written as 8va bassa, 8b, or simply 8vb.
• The abbreviation “8vb” should be regarded as shorthand specifically used by copyists and is not recommended for use in engraved music.

Here’s a table summarizing the distinctions:

Why Use Octave Sign?

Octave sign is especially helpful in music notation because they eliminate the need for many ledger lines.

Essentially, ledger lines are extra lines added above or below the staff for very high or very low notes.

While commonly used in piano music due to its wide range, the use of octave signs on other instruments might be more selective.

Primarily, this depends on the instrument’s range and the composer’s preference.

These signs are used for other reasons:

• Extending Range: They allow composers to write for instruments or voices that may not be able to reach certain high or low notes.
• Creating Specific Effects: Composers may use octave signs to create specific musical effects, such as a brighter or more powerful sound, by playing notes in a higher octave.

Note that these symbols are helpful because they avoid cluttering the staff with excessive ledger lines.

So, using octave signs can provide a cleaner look for such passages. In short, 8va and 8vb make music easier to read and play!

Understanding Context

It’s important to consider the context when encountering octave signs.

In some cases, the composer might specify the duration (how many notes) the octave indication applies to.

Additionally, for instruments with a wide range, the octave sign might only be necessary for a specific section that ventures outside the instrument’s comfortable range.

Octave Sign 8va and 8vb Placement

To ensure clarity and minimize conflicts with other musical elements, the placement of the “8va” or “8va bassa” notation, along with its extender line, should be carefully considered.

It is important to position them as close to the affected notes as possible while avoiding any visual clashes.

The “ottava” indication can be positioned either above the slur or directly on a note within the slur.

In the given example, the “8va” is entirely placed above the slur. However, it intersects the slur in the second example due to a potential limitation of available space.

Handling Octave Signs Across Staves

To handle octave signs (8va and 8vb) when they break from the first staff to the second staff below:

Option 1: Brackets and Extended Lines

When transitioning from one staff to another, the “8va” or “8va bassa” notation undergoes a break at the end of the first staff, aligning with the right barline.

The extender line then resumes just beyond the clef or key signature on the subsequent staff.

This is the most common and clear way to indicate an octave shift across staves:

1. Place the 8va or 8vb symbol at the end of the first staff, either above (for higher) or below (for lower) the last note.

2. Draw a dash line bracket that connects the symbol on the first staff to the beginning of the second staff.

3. Extend a dashed line from the 8va/8vb symbol across the bracket and onto the second staff. This line shows the duration of the octave shift.

4. The notes on the second staff affected by the octave shift are written as if they were in their original octave.

Option 2: Repeat the Sign

Additionally, a courtesy “8va” or “8va bassa” may be provided at the beginning of the second staff when wrapping from one staff to another.

This serves as a helpful reminder to the performer of the octave adjustment.

This method is less common, but acceptable in some cases. Essentially, you simply repeat the 8va/8vb symbol at the beginning of the second staff directly above or below the first note.

However, this might be visually cluttered compared to using brackets.

Here are some additional points to consider:

• If the octave shift applies to only a few notes at the end of the first staff and the beginning of the second staff, you can use brackets and extend the dashed line only for those specific notes.
• When the octave shift continues for multiple measures on the second staff, you can extend the dashed line as needed or rewrite the 8va/8vb symbol at the beginning of subsequent measures on the second staff if clarity is improved.

Ultimately, the goal is to ensure clear communication for the musician interpreting the score.

Both methods achieve this, but using brackets and extending the line is generally considered the preferred approach.

Octave Sign With Accidentals

When using the octave sign “8va” (one octave higher) or “8vb” (one octave lower) with accidentals (sharps, flats, naturals), it indicates that the notes written should be played at the adjusted octave while retaining their accidentals.

If an octave sign applies to a passage, accidentals are still needed for any notes that fall within the new octave range.

In the example above, when “8va” applies to a note with an accidental, like the C-sharp here, the accidental is carried over to the higher octave.

The sharp symbol is connected to the note with a horizontal line, clarifying that it applies throughout the entire duration of the note.

Octave Sign With Rest

If there are brief rests within the 8va or 8va bassa notation, the extender lines for 8va or 8vb markings can continue over short rests within the notation.

However, if the rest notations are longer, break the extender line before the rest and resume it after the rest.

When rests appear before the 8va or 8va bassa notation, begin the alteration on the first note after the rests.

Conversely, when rests follow the 8va or 8va bassa notation, the octave alteration ends with the last note in the group.

The rest of the notations should not be considered part of the octave alteration.

Octave Sign with Loco

These octave signs (8va and 8vb) are used when a passage needs to be played in a different octave for different reasons.

The “loco” sign comes into play after a section with an octave sign.

We use “loco” (meaning “in place” in Italian) along with octave signs (8va and 8vb) in musical notation to indicate a return to playing notes at their written pitch.

Essentially, it tells the musician to stop playing the notes in the higher or lower octave and return to playing them at their written pitch.

Note

Although the termination of an extender line typically signifies the conclusion of the octave instruction, the word “loco” can be added for clarity to indicate a return to the written pitch, thereby canceling the effects of the octave sign (8va or 8va bassa).

This means that the 8va or 8va bassa no longer applies.

Octave Sign on a Single Note

The octave sign, whether 8va or 8va bassa, is positioned above or below the notehead and can be applied to a single note, either as the final note of a piece or in conjunction with other notes.

If it is the concluding note of the piece, the octave sign may or may not be accompanied by a downward or upward stroke.

However, if a single note is altered within the piece but is not the final note, it is imperative to include an upward or downward stroke alongside the octave sign.

What does Quindicesima Alta 15ma Mean?

The symbol “15ma” indicates that the note should be played two octaves higher than written.

“15ma” is a shortened form of the term “fifteenth,” derived from the Italian word “quindicesima” (pronounced kween-dee-CHAY-zee-mah), which adds a fun linguistic element.

This notation is employed to simplify reading music that would otherwise require numerous ledger lines.

Some individuals might question why it is not labeled as “16” since going eight notes higher corresponds to an octave (“8va”).

However, upon counting the number of notes within two octaves, it becomes evident that there are only 15.

Hence, Italians use the abbreviation “15ma” in a manner similar to how English speakers express “15th.”

While 8va and 8vb are commonly used octave signs, encountering 15ma (or “quindicesima”) is quite rare.

Essentially, it instructs musicians to play notes two octaves higher than written.

But due to its wide range shift, composers seldom use 15ma, especially for instruments with a comfortable mid-range like violins or cellos.

It’s more likely encountered in exceptional circ*mstances, perhaps for instruments with a particularly high register.

Coll’ 8va

Coll’ 8va, short for “coll’ ottava,” is an abbreviation used to indicate “with the octave” in musical notation.

It is a shorthand method of denoting octaves, although it is not commonly employed in traditional engraving practices.

The purpose of coll’ 8va is distinct from 8va (ottava alta) in that the written notes are replicated at the octave, effectively doubling their pitch.

To differentiate coll’ 8va from 8va, it is recommended to use a longer dash length or a solid line for the extender line.

This helps to clearly distinguish between the two notations.

When notated in the treble clef, coll’ 8va signifies that the written notes should be played one octave higher.

On the other hand, when notated in the bass clef, coll’ 8va indicates that the written notes should be played one octave lower.

The Rules of 15ma

If you do encounter 15ma, the same principles that apply to 8va also apply here.

This means accidentals (sharps, flats, and naturals) written alongside the notes in the original score should be carried over two octaves higher when playing the passage.

Instrument Considerations for 8va and 8vb in Orchestral/Band Scores

While octave signs (8va and 8vb) are a valuable tool for composers, their use can vary depending on the instrument and the overall score layout.

Here’s a breakdown of instrument-specific considerations:

Space Constraints

In orchestral or band scores where space is limited, octave signs can be crucial for avoiding cluttered notation.

Leger lines, the extra lines added above or below the staff for high or low notes, can become overwhelming and difficult to read when used excessively.

Octave sign 8va and 8vb markings help to maintain a clear and readable staff by indicating octave shifts.

Instrument Preferences

While space limitations often dictate the use of 8va and 8vb, instrument preferences also play a role.

Woodwinds favor leger lines, while violins handle both. Violas and cellos might find extensive 8va markings challenging, requiring a composer’s careful consideration.

Woodwinds

Woodwind instruments like flutes, clarinets, and saxophones are generally comfortable reading ledger lines throughout their range.

So, composers might use them more frequently for these instruments compared to octave signs.

Strings

String instruments have different approaches to octave signs:

• Violin: Violinists are accustomed to reading both leger lines and 8va markings. However, the symbol 15ma (indicating two octaves higher) is rarely encountered on violin parts.
• Viola and Cello:Due to their lower register, violas and cellos can find extensive use of 8va signs challenging to play. Composers should use them sparingly for these instruments, favoring leger lines when possible.

Keyboard Instruments

• Piano: Pianos benefit greatly from octave signs due to their vast range. Composers will utilize 8va in the treble clef for higher passages, 8va bassa in the bass clef for lower passages, and occasionally even 15ma for very high sections.
• Organ: Similar to the celesta, the organ’s range might not necessitate 8vb markings. However, 8va markings are commonly used to indicate higher-pitched passages.
• Harpsichord: Harpsichordists typically rely on leger lines for both high and low notes, with 8va or 8vb being used less frequently.
• Celesta: This high-pitched instrument’s range doesn’t extend low enough to necessitate 8vb markings. However, 8va markings are commonly used to indicate passages played an octave higher.

By understanding these instrument-specific considerations, composers and musicians can ensure clear and efficient notation for orchestral and band scores.

Remember, the ultimate goal is to create a score that is both easy to read and accurately reflects the composer’s intent.
