Songwriting - Part 5

Orchestration: (excerpt from a lesson on Orchestration)
Orchestration is the way timbre is used in musical contexts (songs/compositions). If you have a melody, a bass line and some chords, you can play all of these on a single piano or solo guitar (sometimes). But you can also arrange (orchestrate) these elements (the melody, bass line and chords) for 2 or more instruments. Making the decisions about which instruments will play what notes is the process of orchestrating.
In the past, classical composers almost always composed their own music and also orchestrated it. Today, it is common for composers and songwriters to have other people orchestrate their music for them. If you have ever written songs for more than one instrument, you have orchestrated music. Orchestration is an art, a science and an industry all its own. For the typical songwriter, orchestration is often overlooked, misunderstood or a mystery. We will begin discussing orchestration on an intermediate level (you will need to have a very basic understanding of how instruments work together before being able to get the most out of this lesson.
When using multiple instruments, consider how many different ways you may arrange the placement of each instrument in the pitch range spectrum.
[Pitch range spectrum? What is that?... It is the range of all possible notes from very low notes to very high notes and everything in between.]
It is obvious that bass instruments such as, bass guitar, double bass, tubas, contrabassoons, etc. play the lowest notes (the bass notes) in the vast majority of musical contexts that use these instruments. Composers use these instruments in the bass because:
Because these instruments do play and sound well in low pitch ranges, it is often overlooked that these same instruments can sound great in the tenor range (the pitch range just above the bass range – for example the lowest several notes on a 6 string guitar are in the tenor range). In a typical song (pop, rock, metal, country, blues or jazz) the bass instruments are virtually always playing the lowest sounding notes (the bass notes). Classical music composers of the 19th, 20th and 21st centuries frequently experimented with the role of traditional bass instruments, sometimes placing those instruments higher than (or equal with) tenor or even alto range instruments. This is called “voice crossing” or “crossing voices”. It is generally done as a special effect in the music to bring out contrast in the role and sound of the orchestration.

Voice crossing involving bass instruments is not common in most non classical music, but why?
No, in general, non classical music orchestration has been limited to the basics of instrumentation (the common pitch range of instruments) because bass notes are natural for bass instruments, and because that is the way it has traditionally been done. And yes, the usual way of doing things works just fine, that system is not broken, so why fix it? Crossing voices with the bass is not “fixing” anything, it’s simply another useful tool when used in the right places (and when not overused!) It is a cool sound to use in some situations and many bass players love to play high parts but rarely get a chance to in songs.
When you listen to music, notice how infrequently this technique is used, but when you do hear it, analyze how and where it’s used. If you are looking for it, it is pretty easy to hear.
Experiment with voice crossing the next time you write music. If it does not sound good the first time you try it, don’t give up on the concept if it doesn’t improve the sound of your song. Voice crossing does not work in all musical situations. For example, you are more likely to hear it used in instrumental sections (intros, interludes and transitions for example) or a vocal bridge section. Verses and choruses are less likely to contain voice crossing involving the bass instruments. This is because vocal melodies are generally more important than bass lines and crossing voices with the bass will distract one’s ear from the vocal melody. Composers generally want important vocal lines to be clear and without much conflict for the listener’s attention. But don’t let this stop you. Experiment with each section of your song to see if it works for you.
There are 2 main approaches to bass line voice crossing:
