Percussion in Tracked Music

__Introduction

Hello and thanks for reading my first article for Audiofile. Thanks to basehead for organizing it and getting on my case to write something. :)

In this article I'd like to share some of my ideas about tracking percussion. I'm not going to discuss rhythm or time signatures in this article, but instead how to lay out the individual sounds within your desired drum track.

__Starting out


The first step to creating a percussion accompaniment for a tracked tune is to select your sample set. Depending on the style of music you are writing, you will need to select appropriate sounds which fit into your musical concept. For example, a distorted 909 bass drum doesn't sound good in jazz. Nor is a brushed snare fitting to an industrial song.

Some people also fail to assemble a *complete* percussion sample set. This limits one's ability to create a drum track which varies enough to keep the piece interesting. Here's a listing of a "standard" drum kit used by rock bands:

- Bass Drum
- Snare Drum
- 5 toms, decreasing in pitch [3 toms: 2 raised and 1 floor is also common - Ed.]
- Hi-hat
- Ride Cymbal
- 2 Crash Cymbals

You may want to have multiple samples for each of the above instruments, to help provide different textures. Often people will use more than one tom sample to cover a wider range of pitches without playing a sample out of its "sweet" range.

You also should get at least two hi-hat samples to cover "opened" and "closed" positions. If you can find any samples that would fall between the first two, use it for an even more realistic effect. The position of the cymbals on a hi-hat can change slightly and the resulting sound will be different.

Below are some additional percussion sounds which are more common to orchestral percussion sets:

- Tympani
- Tambourine
- Bongos
- Conga
- Marimba
- Chimes

__Crash Cymbals

Crash cymbals (in real life) contain an initial attack, then a steady and constant fade. I have seen lots of crash cymbal samples that get cut off at the end before a complete fade can be done. There are a few ways to get around this:

Loop the end of the sample and perform a manual fade with volume commands
or volume fading effects once the loop begins. This may be acceptable
for songs where sample space is limited, such as a chiptune, but will
usually not be acceptable for normal standards.

Fade the cymbal with volume commands or volume fading effects before the
end of the sample is reached.

Use echoed cymbal crashes to cover over a sudden fadeout ending

__Sustained Cymbals

A sustained cymbal is one that is used to slowly raise the volume of a cymbal. It is usually played with two small padded mallets. The harder and the faster the cymbal is struck, the louder it will become.

At the end of a cymabl creschendo, it is usually struck once and played as a crash.

Trackers can produce this effect very easily by reversing a crash cymbal sample. However if you're using a sustained cymbal sample that is different from your crash cymbal sample, be sure to get the pitch of the two relatively close.

__Stereo Panning

For this topic I want to go in-depth and explain the method I use for determining how to place a percussion effect into an appropriate position in the stereo panning spectrum.

Typically, there are two ways to pan with this method:

- Pan the instruments as if you were the one playing a drum kit

- Pan the instruments as if you were in an audience

With these two methods, everything would be reversed as you would either be in front of, or behind, a drum set. The description which follows will explain the position of the instruments as seen by a drummer sitting behind a set.

__Layout of a Drum Set

At the center of the drum kit, we have the bass, or "kick" drum which sits on the floor. Above that and directly in front of the drummer is the snare drum. These instruments are fairly common and don't need an introduction. Since these two drums are prominent in most rhythms, and are positioned at the center of a drum set, these instruments should be in the middle of the stereo spectrum.

The hi-hat is best described as two cymbals facing each other, connected to a pole. At the base of this pole is a footpedal which when pressed will bring the cymbals together. This instrument is commonly found on the left side of a drum set.

With a 16-step panning command, I would suggest placing hi-hats about two notches left of center. I have heard people who like to pan alternating hi-hats between left and right. Now, no offense to people who do that, but I just think it sounds silly.

There are different levels of attack on the hi-hat also. Most sample sets just have "opened" and "closed" hi-hat samples. To really spice up your percussion track, try to get several varying hi-hat samples with different attacks.

Toms are drums which are on top of the bass drum, and also on the floor to the right of the bass drum. Starting at the leftmost tom drum, they go downwards in pitch. They don't have as definitave of a pitch as tympani, which can be tuned to a certain note.

Toms are mostly used for fills and solos. When tracking tom drums in your song, begin with the highest pitch panned a bit left of center, and as the pitch decreases, bring it through the middle and to the right of the center.

Ride cymbals are commonly used in place of hihats in a drum beat. A ride cymbal is usually to the right of two toms on the bass drum. I suggest panning it an equal distance from the middle but on the opposite side from the hi-hat.

Crash cymbals usually follow a drum fill or mark the beginning of a new musical section within a piece. Typically, a drum kit would have two crash cymbals (or a cymbal with a similar purpose). There would be one to the left of the bass drum, and above and behind the hi-hat. There might also be one above the ride cymbal.

If one crash cymbal is struck in a piece, it is usually the one on the right, because the drummer is often recovering from a tom-fill at that point, and is in the position to strike the right crash cymbal.

Two crash cymbals panned equidistance from the center can provide a much more dramatic effect. This can help indicate a musical transition.

__Establishing a Panning Range

Another thing to be careful of when panning percussion sounds is where it will fit in the stereo spectrum as compared to the other instruments in your piece. Picture a live band on stage. At the very center and in the back is the drum set. On the left and right are usually stacks of amplifiers.

To give the impression of being similar to a real live band, you might wish to pan your percussion within the stereo spectrum according to how it fits with other instruments in a live performance setting. Using this method, you would use the guidelines discussed above for selecting the approximate position for each instrument, then be sure your entire percussion section is closer to the center than lead voices.

Additional percussion instruments which you might use don't necessarily have to be in the center. Perhaps a backup singer is at the far right of the stage playing a couple bongos, or a tambourine.

__Orchestral Percussion

A percussion layout at an orchestral performance of course will be very different than a typical rock band drum kit. For one thing, there will typically be several percussionists, and quite a few more diversified instruments.

The percussion section at an orchestral performance will be behind all other instrumentalists. Often the percussion setup will take up the full length of the stage.

At the center of the layout is usually a large bass drum, a snare drum, and a cymbal which is often used for creschendos. Off to one side might be a set of tympanis, and the opposite side might have a set of chimes, some bongos or congas, a xylophone or marimba, etc.

To track percussion for an orchestral piece, it should first be decided what instruments will be used. Then in your mind or on paper, create the stage layout. Set up a maximum panning range (which should wider than that for a standard drum kit) and begin positioning the instruments within the stereo spectrum.

__Marimba and Xylophone

You could also use note-range panning on instruments like the marimba and xylophone. Of course with a full percussion setup you wouldn't want to pan it all the way across the center. For the lower half of the note range you could use one panning position, and another for the higher half. This is done to give the feel of different notes coming from different places.

If your song has a fast marimba or xylophone part, consider alternating the volume on every other attack. The percussionist will be playing with two rubber mallets, most likely. Usually the person playing the instrument will have a dominant hand and a weak hand, which will affect the amount of attack.

__Conclusion

These are my thoughts on tracking percussion. I'm certainly no master at it, but I like to think that a well thought-out approach will produce a result you can be happy with. Feel free to send me your comments or thoughts related to this topic.
