Help for Transposing Between Instruments
This article is about transposing music “on paper” for other musicians to read. That’s why there are so many technical details. Not all instruments play in the same written key, so knowing which instruments play in which key is very important, not only for composers and arrangers, but for musicians of all sorts who play in ensembles of any kind. If a musician wants to learn to transpose by sight, knowing these particulars may come in very helpful. The ones that will be the most helpful can be determined mostly with practice and experience. This article is written primarily for a player, but there are a lot of good ideas to help a composer / arranger / music transcriber.
Music has been called the universal language because it speaks across borders and cultures, and is a source of profound joy and inspiration for many. Within this giant world of melodies and harmonies, countless instruments contribute their unique voices to this unique means of human expression. Yet, for musicians, there are moments when the need arises to switch from one instrument to another, each with its distinct tuning. In this article, we will explore the art of transposing between instruments, bridging the gap between their diverse tonalities. This discussion will revolve around the idea of transposing, not only in terms of altering pitch but also embracing the challenge of adapting one's musicality to different instruments. While this journey may initially seem daunting, rest assured, with the right approach and practice, it can be made very doable and become a fulfilling experience.
Understanding the Basics of Transposing:
Before we delve into the specifics of transposing between instruments, let's first establish a fundamental understanding of what transposing really is. At its core, transposing is the process of changing the pitch of a musical piece from one key or tuning to another. This can be necessary for a variety of reasons, such as accommodating different vocal ranges, accommodating the limitations of a particular instrument, or playing alongside other musicians who are using instruments in different tunings.
It can also mean changing the way the note is played on different instruments. The note C on a flute is played as a D on a trumpet, and as an A on a French horn. Baritone horns can play in either the Treble or Bass clef. The middle C played by a baritone reading bass clef would be the first line above the staff. The same player reading treble clef would play that note as a D on the fourth line.
The history of the development of different keys for different instruments is terribly complex. Some of the reasons that instruments have to play in the keys that they do include:
> Several hundred years ago, certain instruments could only play in certain keys, so the composer had to remember that when he began writing a new piece.
> Some instruments play in the key that they do so that their ranges are centered on a particular clef and require as few ledger lines as possible.
> Some instruments, such as the saxophone family, which has five members, were intentionally invented with identical fingerings, but which were set in two different keys to better match the range of the clef in which it is written.
Mastering Music Theory:
To excel in transposing between instruments, it's crucial to have a solid grasp of music theory. Understanding concepts like key signatures, intervals, and chord progressions will serve as your foundation. This knowledge will allow you to make informed decisions when adapting a piece from one instrument to another.
There are a number of conventions that one must use, particularly when transposing “on paper’ for another musician. Here are a few:
> Knowing and understanding the different clefs in which music is written. There are not only the popular Treble or G clef and Bass or F clef, but an alto or C clef, used for violas in which the key signature is placed on the middle line and a Tenor clef, also known as a C clef, but on which the key signature is placed on the fourth line.
> Accidentals usually reflect the marks in the new key signature, whether they are sharps or flats. If you transpose from a sharp key to a flat key, accidentals almost always will be flats and vice versa. Sometimes this will look awkward, but it’s easier for reading musicians to follow. The only exception to this guideline is if there are a number of accidentals in a row and reading the new music would require multiple sharps or flats and even more natural signs. In that case, using a few sharps for accidentals in a flat key is acceptable and vice versa. If the accidental indicates a half or whole step going up, that accidental is almost always notated as a sharp. And if the accidental indicates a half or whole step going down, that accidental is almost always notated as a flat.
> Some songs may not be in a traditional key, e.g., major or minor, but rather in a mode. A good understanding of the most common modes (Aeolian, Dorian, Mixolydian) is always helpful.
Another great tool is a chart, or set of charts, of all the instruments that may need to be transposed in a certain situation. Unless a composer / arranger / transcriber has works with all the instruments for a very long time, the transposing knowledge for some of the less-used instruments can become fuzzy.
Embrace the Challenge:
Transposing between instruments is not merely a technical exercise; it's a creative challenge. Each instrument has its unique timbre and sonic characteristics. When transposing, embrace the opportunity to explore and reinterpret the music. For example, a piece originally written for a piano can take on an entirely new dimension when played on a guitar. And, something written for flute has a whole different sound when played by a sax. This creative aspect of transposing can breathe fresh life into familiar compositions.
Another thing to remember is that many instruments, especially woodwinds, can play a wide range, sometimes three octaves or more. A “happy” or bright song might sound better in an upper range whereas a more somber song might sound better lower.
I have already shared in my last article about my challenging assignment to play the French horn (tuned in F) while reading from second trumpet music (tuned in Bb). Part of the reason I was able to do it was that the conductor simply expected it! See What to Do if Your Band Doesn’t Have Enough Parts .
Practical Steps for Transposing:
Now that we've established the groundwork, let's explore practical steps for transposing between instruments.
1. Identify the Original Key: Begin by determining the key of the original piece. This information will serve as your starting point. This can be tricky sometimes.
> A song with one flat is normally in the key of F. Its relative minor key is D minor. However, it could be in a mixolydian mode based on C.
> You may need to see what the first and/or last chord of the music is. This often works, but not always.
> You may need to see if there are any obvious dominant chords or other chord progressions that can help identify the key.
For transposing purposes, the main thing to look at is the key signature, although these other tips will help in identifying some accidentals and other unusual parts in the music.
2. Understand the Target Instrument: Familiarize yourself with the tuning and range of the instrument to which you're transposing. Here are a few examples:
> If you're moving from a piano to a guitar, know that the guitar has a different range and a different tuning (typically E-A-D-G-B-E). The piano’s range goes well below the low G on a guitar and extends well above the guitar’s highest note. Any transposition might have to include some “folding” of the melody or reassigning the harmony parts.
> The other thing you may need to consider is the fingering or other technical limitations to an instrument. If the music calls for a slur from low A to low C, an average trombone player couldn’t play that. The music would either have to be in a different key or transposed to a different instrument. Faster melodies can be impossible to play in the lowest register of the trumpet. Some woodwind note changes require raising or lowering some interesting sets of fingers that also make faster music lines awkward, if not impossible, to play.
3. Transpose the Key: Using your knowledge of music theory, transpose the piece to the key that suits the target instrument. This may involve raising or lowering the pitch of individual notes and chords. Remember the range of the target instrument. Simply changing the key doesn’t always put the notes in a comfortable, or even a playable, range. A very important thing to remember when transposing apiece that includes a guitar and wind instruments is that a guitar may have the convenience of using a capo or playing bar chords, but a guitarist playing in the key of G and using a capo on the fourth fret makes playing any wind instrument with the guitar virtually impossible. It puts C instruments (flute, trombone, etc.) in the key of B major (Five sharps). Bb instruments (trumpet, clarinet, etc.) in the key of C# (seven sharps). French horns have six sharps. You get the idea.
4. Adapt the Playing Style to the Instrument: This next step should probably be reserved for more skilled players. If you are switching from, say, a saxophone to a clarinet, the playing style will be a bit different. Clarinet parts tend to require a more polished sound, not always, but generally. Sax parts tend to require a more earthy sound. The notes of saxophones, especially those in the lower registers, also tend to “sound” just a bit later than a clarinet, so the notes must be attacked a split second earlier so that they will “sound” at the right time to fit in with the rest of the ensemble. If you would be switching from a trumpet to a trombone, the same thing applies to the timing of the playing of the notes.
5. Listen and Learn: Listen to recordings of the piece being played on the target instrument, if one has been made. Even if there is no recording, since you may be the first to transpose to that instrument, find a recording of the instrument in the style of the music you’re transposing. This will provide valuable insights into the nuances specific to that instrument.
6. Practice, Practice, Practice: As with any aspect of music, practice is key. Dedicate time to practice transposing between instruments regularly. Gradually, you'll become more comfortable with the process. This is true especially if you’re learning to transpose by sight. It helps to do some transposing on paper first to get the hang of the process. I want to emphasize the use of real paper and pencil for this process. Studies have demonstrated that people learn and remember better when using paper and pen or pencil.
In conclusion, transposing between instruments is a skill that requires dedication and practice, but it also offers a rich and rewarding experience for musicians. As you navigate this journey, remember to embrace the creative possibilities that transposing presents. Transposing involves aspects of math, including geometry, science, and spatial concepts associated with engineering and building. In the end, transposing between instruments is not just about changing keys; it's about expanding your musical horizons and exploring the boundless potential of music itself. So, pick up that new instrument, and let the symphony of your musical journey continue to unfold.
