![]() ![]() For example, a double whole note (or breve) lasts twice the duration of the whole note, a half note lasts one half the duration, and a quarter note (or crotchet) lasts one quarter the duration.Ī related symbol is the whole rest (or semibreve rest), which signifies a rest for the duration of a whole note. Other notes are multiples or fractions of the whole note. Since it is equal to four quarter notes, it occupies the entire length of a measure in 4 The whole note or semibreve has a note head in the shape of a hollow oval-like a half note (or minim)-but with no note stem (see Figure 1). In this last score, I just put different combination of rhythm feeling 4 beats.A whole note (American) or semibreve (British) in musical notation is a single note equivalent to or lasting as long as two half notes or four quarter notes. In this piece, each measure contains 4 beats : it can be 8 eighth notes, or a whole note. In this piece, each measure contains 3 beats : it can be 3 quarter notes, or 6 eighth notes, or any combination leading to 3 beats. The boundaries of the measure are indicated by vertical bar lines. It means that we make groups (ie measures) of 4 beats.Ī measure (or bar) is a group of note, that has a length specified by the time signature. In this piece, the time signature is 4 *(remember, for now we don't care about the lower number)*. It means that we make groups (ie measures) of 3 beats. In this piece, the time signature is 3 *(remember, for now we don't care about the lower number)*. Have another look at those excerpts, and see how the time signature is written. The time signature is written at the beginning of a piece. If it is a grouping by 4, like in a waltz, it's 4. ![]() ![]() If it is a grouping by 3, like in a waltz, it's 3 The upper number simply correspond to the kind of grouping. (Sometimes, the lower number is 8, meaning "one beat = on eight note"). It specifies how many beats are to be contained in each measure (upper number) and which note value correspond to one beat (lower number).įor now, the lower number will always be 4, since we work with the convention "one beat = one quarter note". The time signature is a set of two numbers. Definition of time signature and measure. If you choose to write a traditional rock, you should choose to group notes by 4.Īs a rule, the time signature you choose when writing music should correspond to the musical idea you have in mind. So if you are writing a traditional waltz, you should choose to group notes by 3. When writing music, we want the score we write to reflect the musical idea we have in mind. How do I choose to group notes by 3, or by 4 ? We group notes using measures What amount of note will a measure contain ? So, to be clear : Why do we have to group notes? (when writing)īecause it's way easier to read that way. Ofcoursewecould,butyoucouldalsowritewithoutblankspacesbetweenwords!! Made my point? Why do we want to group notes when writing ? We could just simply write notes one after the other, right ? This feeling of "groups of notes" is transcribed on the score. (in 5, in 6, in 7, etc) Why do we need measures ? As an example, most nowadays western pop tunes are written in 4.īut there is a LOT of wonderful music, from ALL PARTS of the world, written (or just played and sung) with completely different groupings. The most usual way to group notes is grouping by 4. In this score I've written a few bars of a common left hand piano boogie woogie pattern.Ĭan you feel the 1-2-3-4, 1-2-3-4? Other grouping ? (a waltz is a famous dance usually based on a 3 beats patterns)įrom measure 5 (we'll talk about what is a measure right after that) to the end, you can strongly feel the 1-2-3, 1-2-3 pattern. Listen to this excerpt of the Waltz in D♭ Major, by Frédéric François Chopin (1810 - 1849) : So yes, it does exist, with or without notation. The time signature defines, in a way, how we group notes. One of the main characteristic of a song, or any piece of music, is the time signature. I recommend that you first read the previous post, where we discussed basic rhythm figures, such as quarter notes, eighth notes, and so forth, right here.įeel free to read (and re-read) the paragraphs of this post in any order, since it can be a bit hard to fully understand it. In this post we will talk about measures (or bars) and time signature.
