How to determine the genre of a song?
I listen to many songs and I always wonder how the genre of a song is determined. Is it by listening to the song, or by the song's info like the artist, year released and so on?
Do you mean just by listening or looking at the year when it was written is allowed (and getting other info from the cover)?
I meant by listening. Does the year when it is written also factor into determining the genre?
Well, new musical styles are created all the time, so it's reasonable to assume that nothing Bach wrote could be designated "rapcore". But there are plenty of works created now that follow old established styles and are thus in the same genre.
lol I understand. I mean by listening or based on the basic info of the song(like year) or both. I would prefer a way just by listening if possible.
I wish there was a good answer to this question... but I honestly don't believe it is possible to answer it, especially not easily and especially not definitively. It's akin to any number of philosophical questions like "What is Knowledge?" Further, limiting the answer to "by listening" introduces way to much subjectivity.. the answer will almost always degrade to "I know it when I see it". Basically, genre taxonomy is really really difficult (see, i.e., http://blog.echonest.com/post/52385283599/how-we-understand-music-genres ).
Here at Brazil, Jai Ho is considered as Hindi or Indian gender.. But for local culture we have many genders, but generally we classify just with MPB (Popular Brazilian Music).. sorry about my english :D
I down voted this because I think this question needs to be edited. First of all it asks multiple questions. Do you want to know what the genre Jai Ho is, or how to determine the genre of a song? Also the last sentence says "I am looking for a simple way to determine the genre." To me this should be left out since its subjective who is to know what is 'simple' to you. I think the question should read "How to determine the genre of a song by listening to it?" or something along those lines. I think if these issues were fixed it would be a great question.
@ChrisR I want to know How to determine the genre for any song. The example I gave because I thought anyone who answers would take that example and explain a step by step process to determine the genre. Please edit the question to improve it if its not clear. My native language is not English.
The description of a genre is a collection of patterns. Songs that share patterns can be grouped in a genre that describes those patterns. You can find these patterns in any music dynamic: rhythm, speed, progression, key, instrumentation, whatever.
You determine the genre of a song by identifying these patterns, and associating them with the description of a genre.
For example, let's create two genres: fast music and slow music. Any music below 120 bpms (beats per minute) is slow music, anything faster belongs to the fast music genre. Listen to X song, count how many beats you heard in a minute, and group it the genre it belongs to. Genres work exactly like this, but with many more associated characteristics.
For another example, let's define two genres. I'll just use over-simplified definitions to make the point clearer.
Techno: Little harmonic and melodic movement (if at all). Emphasis in rhythm and percussive instruments. There is small variation through the song (no climax, no distinctive sections, for example).
Trance: Both melodic and harmonic movement. Emphasis on bass, and time-based effects like reverb and delay. Sometimes features string-ensemble-like synthesizers (known as pads). There is variation through the song (it has well-defined intro, break-down, climax, and other sections).
Both Techno and Trance: Loop-based electronic music, based on samplers and synthesizers, carved for the dance floor.
Listen to this:
There is no harmonic movement, with some melodic movement, which repeats through the song. The movement is injected through the timbre of the melody part, and the percussion part. There is little variation through the song, with no distinctive sections. This song is a good fit for our simplified techno definition.
Now listen to this:
There is harmonic and melodic movement. It has distinctive sections (intro, break down and start of build up at around 3:50, climax at around 5:30, outro). A lot of reverb and delay is being used. This is a good fit for our Trance genre, even if it doesn't feature pads.
Sometimes it's hard to draw an objective link and define a genre objectively, so the genre subject is often a source of debate.
Since musicians can be very creative, not all songs have a specific and defined genre. Some are a combination of many, others present a new pattern with no associated genre at all (for example, in our fast-slow music example, what do we do with songs that have no evident tempo, or songs with variable speed, or a song that can be described at more than one speed like 80 and 160 bpms?). In contrast, there are songs that share well-defined patterns (by tradition, convention, influence, whatever) and are easier to catalog.
