Read Key Signatures in Music
Friday, October 2nd, 2009
Ready to tackle the next lesson for learning to read sheet music? Musical key signatures are not all that difficult to understand when put into perspective. Just like a scale, music notes go up and down but in half steps instead of full.
Natural notes appear by themselves in written music. But sharps and flats have their own symbols:
 |
Sharp |
 |
Flat |
On a keyboard, a sharp note is the black key that’s one note higher than its natural counterpart (the white key). A flat is a black key that’s one note lower than its natural counterpart.
When sharps and flats are written into music as needed (next to the notes), they’re called accidentals. But sometimes they are shown at the beginning of a stave, right after the clef. In this case, they indicate a key signature.
Key signatures show which notes are to be played or sung as sharps or flats throughout the song. So if there’s a sharp sign on “F” and one on “C”, every “F” and “C” note throughout the song should be played as a sharp. There will be no “F” or “C” natural unless specifically indicated by a natural symbol:

Natural |
Key signatures (in this case, D Major) indicate the general tone of a song, as well as where its basic scale begins and ends. For example, a song in the key of D is based on the D Major scale, which begins and ends with “D” — with “F” and “C” played sharp throughout. However, the same song can be written and played in different keys.
Key signatures are a type of musical notation that indicate which key the song is to be played in. But key signatures, despite the name, are not the same thing as key.
Key signatures are simply notational devices; just as a note is the notational name for a pitch, key signatures are the notational names for keys. It is what it says it is: a signature, a simple piece of information that tips you off to the physical form (the key) to be played.
What does it mean to be “in the key of F”, or “in the key of Bb”?
It means that the composer based the composition on the scale of F (which has 1 flat in it), or the scale of Bb (which has 2 flats in it).
Key signatures appear right after the clef (before the time signature) and show a sharp or flat on the line or space corresponding to the note to be altered. Key signatures placed at the beginning of songs will carry through the entire song, unless other key signatures are noted after a double bar, canceling out the first.
For instance, it’s entirely possible to start a song in the key of F but end it in the key of E flat; it all depends on the key signatures and where they’re placed throughout the song (a key signature can change at any point).
Accidentals can also show up throughout a song and only once or twice flatten or sharpen a note that was not previously indicated; this cancels out the key signatures, as well, but only temporarily, for as long as the accidental lasts.
Beginners just learning to read music often have a hard time with key signatures because the key itself is not expressly written, and it’s sometimes difficult to remember what goes where.
Key signatures with five flats or sharps have been known to terrorize new musicians — how in the world, they think, are we supposed to remember all these note changes while we’re playing the song?
It’s obviously possible, though, and there are some rules that can help beginners identify and remember the key as it relates to the key signatures, rules that go beyond rote memorization. If there is more than one flat, the key is the note on the second to last flat.
If there are any sharps at all, the key is a half step up from the last one noted. F major, a key frequently found in beginning sheet music, only has one flat (B), and C major has no sharps or flats at all. Key signatures, when viewed in light of these rules, are much easier for beginners to digest, ensuring that a proper knowledge of key signatures is on its way through the door.
One fact that most people don’t realize is that sharps and flats always occur in the same order:
The order of the flats is B, E, A, D, G, C, F.
The order of the sharps is just the opposite — F, C, G, D, A, E, B.
So if there is one flat in the key signature, it is always B. If there are two flats in the key signature, they are always B and E. Three flats are always B, E, and A. Four flats in a key signature spell the word BEAD. And so on.
It’s the same in sharps, too, except backward. If there is one sharp in a key signature, it is always F. Two sharps in a key signature are always F and C. Three are F, C, and G. And so on.
So once you have memorized the order of the flats, all you have to do is apply the rule mentioned earlier: the next to the last flat is the name of the key. For example, if you have four flats in a key signature, they are Bb, Eb, Ab, Db. The last flat is D, so the next to the last flat is A. So the key is Ab.
With sharps, just mentally go up 1/2 step from the last sharp, and that is the key. For example, if a key has 4 sharps, they are F#, C#, G#, D#. One-half step above D# is E, so the key is E.
Memorize the order of the flats and sharps and those two simple rules, and you’ll be able to identify what major key any song is in quickly and easily

Music Education Can Help Children Improve Reading Skills
Thursday, September 3rd, 2009
Children exposed to a multi-year programme of music tuition involving training in increasingly complex rhythmic, tonal, and practical skills display superior cognitive performance in reading skills compared with their non-musically trained peers, according to a study published in the journal Psychology of Music.
According to authors Joseph M Piro and Camilo Ortiz from Long Island University, USA, data from this study will help to clarify the role of music study on cognition and shed light on the question of the potential of music to enhance school performance in language and literacy.
Studying children the two US elementary schools, one of which routinely trained children in music and one that did not, Piro and Ortiz aimed to investigate the hypothesis that children who have received keyboard instruction as part of a music curriculum increasing in difficulty over successive years would demonstrate significantly better performance on measures of vocabulary and verbal sequencing than students who did not receive keyboard instruction.
Several studies have reported positive associations between music education and increased abilities in non-musical (eg, linguistic, mathematical, and spatial) domains in children. The authors say there are similarities in the way that individuals interpret music and language and “because neural response to music is a widely distributed system within the brain…. it would not be unreasonable to expect that some processing networks for music and language behaviors, namely reading, located in both hemispheres of the brain would overlap.”
The aim of this study was to look at two specific reading subskills – vocabulary and verbal sequencing – which, according to the authors, are “are cornerstone components in the continuum of literacy development and a window into the subsequent successful acquisition of proficient reading and language skills such as decoding and reading comprehension.”
Using a quasi-experimental design, the investigators selected second-grade children from two school sites located in the same geographic vicinity and with similar demographic characteristics, to ensure the two groups of children were as similar as possible apart from their music experience.
Children in the intervention school (n=46) studied piano formally for a period of three consecutive years as part of a comprehensive instructional intervention program. Children attending the control school (n=57) received no formal musical training on any musical instrument and had never taken music lessons as part of their general school curriculum or in private study. Both schools followed comprehensive balanced literacy programmes that integrate skills of reading, writing, speaking and listening.
All participants were individually tested to assess their reading skills at the start and close of a standard 10-month school year using the Structure of Intellect (SOI) measure.
Results analysed at the end of the year showed that the music-learning group had significantly better vocabulary and verbal sequencing scores than did the non-music-learning control group. This finding, conclude the authors, provides evidence to support the increasingly common practice of “educators incorporating a variety of approaches, including music, in their teaching practice in continuing efforts to improve reading achievement in children”.
However, further interpretation of the results revealed some complexity within the overall outcomes. An interesting observation was that when the study began, the music-learning group had already experienced two years of piano lessons yet their reading scores were nearly identical to the control group at the start of the experiment.
So, ask the authors, “If the children receiving piano instruction already had two years of music involvement, why did they not significantly outscore the musically naïve students on both measures at the outset?” Addressing previous findings showing that music instruction has been demonstrated to exert cortical changes in certain cognitive areas such as spatial-temporal performance fairly quickly, Piro and Ortiz propose three factors to explain the lack of evidence of early benefit for music in the present study.
First, children were tested for their baseline reading skills at the beginning of the school year, after an extended holiday period. Perhaps the absence of any music instruction during a lengthy summer recess may have reversed any earlier temporary cortical reorganization experienced by students in the music group, a finding reported in other related research. Another explanation could be that the duration of music study required to improve reading and associated skills is fairly long, so the initial two years were not sufficient.
A third explanation involves the specific developmental time period during which children were receiving the tuition. During the course of their third year of music lessons, the music-learning group was in second grade and approaching the age of seven. There is evidence that there are significant spurts of brain growth and gray matter distribution around this developmental period and, coupled with the increased complexity of the study matter in this year, brain changes that promote reading skills may have been more likely to accrue at this time than in the earlier two years.
“All of this adds a compelling layer of meaning to the experimental outcomes, perhaps signalling that decisions on ‘when’ to teach are at least as important as ‘what’ to teach when probing differential neural pathways and investigating their associative cognitive substrates,” note the authors.
“Study of how music may also assist cognitive development will help education practitioners go beyond the sometimes hazy and ill-defined ‘music makes you smarter’ claims and provide careful and credible instructional approaches that use the rich and complex conceptual structure of music and its transfer to other cognitive areas,” they conclude.
Complete sentence: With superior cognitive development, children may grow into fine students later in their life who can apply to any first-class california business schools they wish.
