NReilingh gave a good general-case answer. I'll give you a specific case just to demonstrate that the concept is useful. First consider a C major chord. C-E-G, right? Then you make it into a minor chord by flattening the third, to get C-E♭-G. So far, so good. Now, consider an A♭ major chord: it's spelled A♭-C-E♭. But what happens when ...

Anacrusis (pickup) is a bit more rhythmic than melodic. Hearing it seems easy to my musical brain, but I can understand how it would not be. Most music has a set rhythm, which we can understand in its simplest form by saying there is a fairly low number (most commonly 4), to which one can repeatedly count while listening to a piece of music such that the ...

My PhD is in Music Composition, but it was a heavily theory-focused program. I also have many theorist colleagues. Your question is interesting, and difficult to answer in total detail without writing a book, so I won't try to be exhaustive. Let me first say that the understanding of "Music Theory" is most definitely not complete, and that there absolutely ...

In the full score here http://imslp.org/wiki/30_Etudes_for_the_Double_Bass_(Simandl,_Franz) (top of page 29) there is no accidental on the C. The OP's image is apparently a different edition - the dynamic markings are also different. I call "typo", and/or "poor editing and proofreading".

B and Cb are different notes. One is a kind of B and the other is a kind of C. Information about harmony is contained both in the note name and any accidental alterations to it — C to any kind of E is a third, and C to any kind of F is a fourth, and those intervals have different meanings, even if they sound "the same". And these pitches are only the same ...

As the other answers have correctly pointed out, you can do what sounds good to you. But this might leave you with a feeling of not knowing where to start. That's why I would like to let you know the little trick used in Lithium and zillions of other songs: you can mix the chords from the major scale and its parallel minor. In the case of Lithium you have ...

A semibreve rest CAN be used in 6/8 time - or ANY time (apart from 4/2 - quite unusual)) to represent one bar's rest. At that point, it isn't actually a 'semibreve', but represents just one bar of that music. It's become a shorthand way of saying "one whole bar rest".

Theory is not a set of rules to be followed or broken. Theory is a set of explanations for why things sound the way they do. As a composer you use theory to help inform your choices, but it never dictates anything.

First off, everything is allowed in music. Whether it's appropriate can be another question, but especially in rock most people basically go by “if it sounds good, it's ok”. Even by the rules of classical counterpoint, it's not forbidden for two voices to share a single note, as long as they don't move parallel in unison. In two-voice ...

This is definitely an error. I would stay away from whomever edited / published this music. Nothing is vertically aligned and the print quality is abhorrent.

There are note values not notateable without ties. For example: A note the length of a crotchet (quarter note) + a semiquaver (sixteenth note) would need to be written with a tie, as there's no notation which says "add a quarter of the length of the note to its duration". We've got "add half" (dotted notes) and "add three quarters" (double dotted notes), ...

C sharp major has seven sharps, D flat major has five flats. Out of the box, the latter is preferable. The former may be more appropriate when there is more material requiring "flattening" the key signature than otherwise. Now major is a rather sharp mode, so it's not quite unlikely. For example, a "proper" fully diminuished chord in C sharp features ...

A semibreve rest is the symbol to be used for "whole-bar rest", regardless of the meter. A whole-bar rest is also distinguished by being written in the middle of the bar rather than being aligned with beat 1 in other staves or voices. This exalted central bar position is otherwise only used by "bourdon" notes carrying multiple syllables in free meter, like ...

Technically, there could be, you just keep extending the pattern. You could even keep extending it to the point where you need to start using double flats, though this is almost never done in practice. The key of F contains: B♭ The key of B♭ contains: B♭, E♭ The key of E♭ contains: B♭, E♭, A♭ The key of A♭ ...

First, I don't agree with that interpretation personally (if that's what Chopin had wanted, he would have written it that way, meticulous soul that he was), so I wouldn't put too much stock in how something "should" be played. In this etude, the voices are this flying passage and the melody in the bass. Breaking it up further is artificial-sounding. ...

The simplest metric, and probably the most frequently used (even if only implicitly), is to count the number of steps between the chords' roots along a one-dimensional line of fifths (or the circle of fifths, if you permit enharmonics and modular arithmetic). I say this is the most frequently used because chord progressions where the root ascends or descends ...

Yes, that is exactly a chord. This is really common in choral songs. For instance, here is a chorale by Bach: The chorales were sung by 4 groups of voices. Notice the first 4 vertical notes: G,B,D and G. This forms a G major chord. The second group of vertical notes is: F#,A,D and A which forms the D major chord and so on. This is also used by ...

It's more about context than it is about written music. It's called a third because it's the third step in the scale. Take the C major scale for example. 1 2 3 4 5 6 7 C D E F G A B The C major chord is C E G: the first, third, and fifth steps (degrees) of the C major scale. It's the same case with minor triads. Here is the C minor scale: ...

Both C# minor and E major keys have the same key signature, so there is no difference there. This relationship is called 'relative key'. Each major key has a relative minor one, with the same key signature (to find it, descend a minor 3rd or ascend a major 6th from your tonic). Similarly for the minor key. To sum up the difference: These two keys have the ...

It certainly holds some truth, irrespective of tuning system, in this sense: modulating to a key with more sharps evokes a “bright” sensation; modulating to more flat evokes a “dark” sensation. This is somewhat tangible: raising accidentals are likely to be perceived as “uplifting”. (Except when they're not; perception is ...

It is not necessary to double the root when converting guitar chords to piano chords but it could be done if fits better with the music. But there are important distinctions between the guitar and piano that come into play when considering how to notate chords on sheet music. These distinctions center around (and are affected by) the way chords are played ...

No the difference is not subtle, but rather basic: a triplet is a note length modification, so three notated eights use just the time for two standard eights. But all notes are visisble in the score. a trill is a kind of ornamentation. Instead of a long (e.g. full note) one plays something like alternating 16ths from the note above the printed one and the ...


13

You retain the accidental. In this case, it is pretty unambiguous since the lead note is immediately preceding the note (baroque trills would even start with the upper note). If there is more of a distance to the preceding use of a changed pitch, one would lean towards adding a reminder accidental to the trill.


13

TL;DR: No. You can use anything you like, as long as it sounds good to you. You can use many scales or not use any; you can use chords from some scale or use chords outside that scale. Just experiment with the theory knowledge you have and you'll see that the rules are made to be broken. You can use them when you want (or need) to, but when you are ...

It is, I think, a perfectly clear observation that one note an octave above another note sounds as if it were the same in a certain sense. It's certainly common for people to perceive things that way, but it's not universal. Here's a question from someone who complains that they don't hear things that way, for example! shared harmonics alone can't be ...


12

Yes it is possible to have a note that is part of a triplet and dotted for example: In this we're using quarter note triplets. Instead of having them all be 3 even quarter note triplets the first one is dotted and the second one is shortened giving us a triplet consisting of a dotted quarter note followed by an eigth note followed by a quarter note to ...

You need to think of that measure as if it were two instruments playing. The higher of the two is playing a dotted "Β" which lasts for 3 beats, while the lower voice is playing an "Ε" for 2 beats and a "D" for the third beat. It all works out exactly when you look at it that way.


12

You are exactly correct that it is the logarithmic nature of pitch that causes this effect. In cases like this, I find that a picture is helpful. Here I've labeled equally spaced octaves (1200 cents) along the x-axis (representing pitch). I've then labeled the corresponding frequencies on the y-axis as multiples of some arbitrary base frequency f. Note that ...
