In this slideshare we’re going to look at the family of string instruments, including their tuning, ranges, and available articulations.
It might sound obvious, but whether you’re working with real instruments or sample libraries, knowing about the instruments you’re writing for is going to improve your music infinitely. So many composers simply open a “Full Strings” patch in their DAW and then can’t figure out why their strings don’t sound right, or realistic. While arranging for strings is a slightly more involved skill, some knowledge of ranges, articulations, and timbre of the instruments will help you make more informed decisions in your writing, and will open up a whole new world of expression to you.

2. String Instruments
It might sound obvious, but whether you’re working with real
instruments or sample libraries, knowing about the
instruments you’re writing for is going to improve your music
infinitely.
So many composers simply open a “Full Strings” patch in their
DAW and then can’t figure out why their strings don’t sound
right, or realistic.
While arranging for strings is a slightly more involved
skill, some knowledge of ranges, articulations, and timbre of
the instruments will help you make more informed decisions in
your writing, and will open up a whole new world of
expression to you.
5. The String Family
The instruments in the string family include:
• Violin
• Viola
• Violoncello (or cello)
• Double bass (or contrabass)
6. The String Family
The harp is also part of the string family, but I will cover that in a
separate section due to its vastly different playing method.
Although it varies from project to project, and depending on the exact
sound a composer is aiming for, a standard modern orchestra string
section comprises of:
• 30 violins (split as 16 “first” and 14 “second” violins)
• 12 violas
• 10 violoncellos
• 8 double basses
8. Ranges & Tunings
NOTE: When describing ranges and tunings I am using
conventional MIDI numbers to describe the octave, as
opposed to the traditional octave descriptions.
Therefore you should assume “Middle C” to be “C3”
9. Violin
The smallest of the string instruments, the violin has four strings, tuned to:
• G2
• D3
• A3
• E4
The lowest note of a violin in standard tuning is G2, and the highest is E6 –
although some violins may be designed to allow players to go higher. Many
sample libraries actual limit the highest note to C6; bear that in mind when
composing if your piece is being created with samples!
Violin parts are written in the treble clef.
10. Viola
Often the most overlooked of the string instruments, the viola is tuned one
fifth below the violin, so standard tuning is:
• C2
• G2
• D3
• A3
It’s range spreads from C2 up to around G5 – again, some models will allow
higher notes, but sample libraries are often limited to D5.
Most viola parts are written in the alto clef, unless the part is in the higher
register for an extended period, in which case the treble clef can also be
used.
11. Cello
The cello is tuned one octave below the viola, and is often seen as one of the
most beautiful sounding string instruments:
• C1
• G1
• D2
• A2
Due to its longer fingerboard the cello’s range is larger than its smaller
siblings’: from C1 all the way up to C5.
Cello parts are written in the bass clef, unless (as with viola) there are
extended section in a higher register, in which case the tenor clef can be used
to avoid ledger lines.
12. Contrabass
Guitarists and bassists may finally see something familiar here. The tuning of
the double bass is the same as the bass guitar or first four strings of the
electric guitar – the only member of the string family to be tuned
in fourths rather than fifths:
• E0
• A0
• D1
• G1
Many modern orchestral double basses have what’s called a “C Extension” –
allowing the range to be extended down to C0. The highest practical note is G2.
Double bass parts are written in the bass clef, and sometimes the tenor clef.
14. Technique/Articulation
It is very important to remember that string instruments can
make alterations to notes while the note is being played.
This may sound obvious, but if you’re composing at the
piano/keyboard it is easy to forget that a string player is
able to increase or decrease their dynamics and intensity of
vibrato while sustaining a note – using these effects can
dramatically improve your orchestration and add some real
flavour to your pieces.
So don’t forget about crescendos (getting louder) and
decrescendos (getting quieter) – big swells always sound
amazing!
15. Technique/Articulation
The articulations and techniques are generally the same across all of the string instruments,
and include, amongst many others:
• Legato
• Nonlegato
• Staccato/Spiccato/Martellato
• Marcato
• Pizzicato/Slaps
• Col Legno
• Harmonics
• Glissando/Portamento
• Double Stops
16. Legato
Much like how vocal “melisma” is the singing of one vowel
over multiple notes, the “legato” articulation is the
playing of multiple notes over one bow stroke.
This creates fluid sounding passages.
Obviously, the player will need to change bow direction
at certain points, so think carefully about the phrasing
of your passages and where you would like more detached
notes vs fluid notes.
Non-legato or détaché is basically the opposite.
17. Staccato/Spiccato/Martellato
Staccato is where the notes are much more “detached” –
think “bouncy” and you’ll get an idea of the effect.
Spiccato is a more emphasised form of staccato, where the
player literally bounces or springs the bow off the
string.
Martellato is the opposite: the bow should not leave the
string, but has a very abrupt start and stop that can
give a more “aggressive” sound.
18. Marcato
Marcato basically implies an accent on every note.
Each note is played more forcefully and intentionally,
giving a very pronounced effect.
19. Pizzicato/Slaps
Pizzicato is where the string is plucked instead of bowed.
Unlike the guitar, when a violin/viola/cello/double bass is
plucked the sound dies away very quickly.
Therefore, pizzicato gives a very light, quite empty sound.
At its softest it is a delicate, harp-like pluck.
At its hardest it becomes a “slap”, sometimes called a
“Bartok” pizzicato (named after the composer).
This is where the string is plucked so hard that it physically
slaps the fingerboard.
20. Col Legno
This one can make you pretty unpopular…Col Legno is where
the player turns their bow upside down and whacks the
strings with it.
So instead of using the “hairs”, they’re hitting the
strings with the wooden part of the bow.
A great effect, but players with expensive instruments
won’t thank you for employing it.
21. Harmonics
If a string player lightly places their finger on the
string while bowing a variety of high pitched noises can
be heard, called “harmonics.”
Depending on where the finger is placed, these can be
quite subtle (like one octave above the note) or not
(like 5 octaves above a note!)
22. Glissando/Portamento
Another great effect that can be done on strings is
glissando or portamento.
This is where the player “slides” between two notes.
Instead of a sudden note change, the pitch gradually
shifts up or down to the new note.
This can be done at various speeds and distances – even
across strings (but the string switch would usually be
noticeable).
23. Double Stops
These are chords for string instruments!
A string player can easily bow two strings at once to
create chords – you just have to think logically about
the physically possibilities (e.g. wide intervals are
often less practical, unless one of the notes is an open
string).
Players can even bow across three strings, but that
requires a lot of pressure on the strings so is therefore
only suitable for short, louder chords – brilliant for
solos.
