According to a group of researchers from the BNM Institute of Technology in Bangalore, India, “timbre stimulates human energy levels without regard to rhythmic or harmonic saturation. ![]() Timbre, the tonal component of a piece created by harmonics, is a curious indicator of mood. Higher overall pitch can be an indicator of happiness, carefree and light moods within a song, while lower pitch implies a darker, sad, and serious tone. Loudness, or intensity of a song can be connected with anger, while softer songs would suggest tenderness, sadness, or fear (Bhat et al 360). Source: Derived from Bhar (2014).įaster tempos are associated with high-energy songs, and slower tempos with lower energy, sadder songs. The eight categories created by Thayer’s model include the extremes of the two lines as well as each of the possible intersections of the lines (e.g. The model divides songs along the lines of energy and stress, from happy to sad and calm to energetic, respectively (Bhat et al 359). ![]() ![]() In most existing methods of music mood classification, the moods of songs are divided according to psychologist Robert Thayer’s traditional model of mood. Breaking a song down into quantifiable musical components such as rhythm, harmony, and timbre can allow for the matching of songs to specific categories based upon expected data for each type of mood. The mood of a piece could also improve upon algorithms for identifying similar songs for online radio services like Pandora, basing the similarities on the song’s mood rather than on similar artists. Identifying the mood of a piece automatically would be extremely useful for sorting large collections of digital music such as those of iTunes or Spotify. Attempting to categorize music through engineering techniques is challenging, but can potentially help to minimize these discrepancies between listeners in the sorting process. Much of the current organization for songs is based on an artist’s overall genre, rather than on the feeling generated by a song. The classification of music can be a difficult task since the emotional reaction between listeners can be fairly different for a given song. This article will discuss the engineering methods used to create these analyzation algorithms, and look at some of their results. These methods can be useful in determining the genre of music automatically for sorting large collections of digital music such as iTunes or Spotify. The method used then is to decide upon certain base songs that very closely embody a certain mood, and to match songs to these specific categories. The emotional reaction to music is different for every person, so analyzing it will not likely yield perfect results. Now you know a little secret, and it's time to apply it to your own videos.įor more great tips from Peter McKinnon check out his YouTube channel.The article will cover the analysis of music using various DSP and music theory techniques involving rhythm, harmony, and spectral features. You will be amazed how frequently those techniques are used by great directors, cinematographers, and editors. Next time when you watch videos or films created by masters of the craft, take a look at those aspects of the story. Usually, warm tones tend to evoke more positive emotions while cold and blue tones get the viewer into the blues. Shooting footage with a given white balance doesn't mean it can't be changed in post to tweak the planned in-camera tone. Same words, same information, but different visuals. In the video, McKinnon shows how introducing the topic of the video in a low-contrast, soft-light environment feels totally different than doing it in a cold, under-lit scenario. This way you can increase the production value of your video without having to actually shoot police cars or ambulances.Ĭhanging the light in-camera or color grading the footage in post is one of the most common visual ways to change the mood of the story. Even without showing the sources of these sounds, our imagination adds them subconsciously. In this video, McKinnon adds siren sounds to a footage of a running man. ![]() Adding background sounds, even without showing anything that produces them in the frame, may work wonders in our imagination. Simply changing the background music can tell a different story to the viewer. SoundĪudio is one of the most important aspects in you video. There are other examples of frame rate changing look and feel, but that's one of the most common uses. In the current example, normal video speed even may look like you want to set a feel of urgency, especially when combined with non-stabilized camera movement. Slow motion may make the video look cool, bring drama, or allow the viewer to focus more on the details over an extended time period. In a nutshell, for most beginner filmmakers this could be the difference between slow motion and normal speed. In his new video McKinnon shows several components that are keys for setting the tone of your visual story.
