Right motor and premotor regions were highly active in the more difficult condition of the transposing task. Frontal-occipital connections were highly active during transposing, but not during math calculations. Magnetoencephalography (MEG) was sensitive to differences of task and working memory load. We compared brain activity during high and low working memory load conditions of musical transposing versus math calculations in classically trained musicians. Because musical transposing involves mental adjustment of notes up or down by a specific amount, it may share cognitive elements with arithmetical operations of addition and subtraction. Musical transposing is highly demanding of working memory, as it involves mentally converting notes from one musical key (i.e., pitch scale) to another key for singing or instrumental performance. 6Department of Physics, Oakland University, Rochester, MI, United States.5Department of Neurology, Henry Ford Health System, Detroit, MI, United States.4Department of Critical Care Medicine, Taipei Veterans General Hospital, Taipei, Taiwan.3Institute of Brain Science and Institute of Clinical Medicine, National Yang Ming Chiao Tung University, Taipei, Taiwan.2Department of Neurology, Wayne State University, Detroit, MI, United States.1Department of Communication Sciences and Disorders, Wayne State University, Detroit, MI, United States.
In terms of frequencies, a semitone is equal to a frequency ratio of 2 1/12 (approximately 1.0595) for equal-tempered tuning.Ching-I Lu 1*, Margaret Greenwald 1,2, Yung-Yang Lin 3,4* and Susan M. From C to B, there's a half (one semitone).From B to C, there's a whole tone (two semitones).From G to A, there's a whole tone (two semitones).From F to G, there's a whole tone (two semitones).From F to F, there's a half (one semitone).From D to E, there's a whole tone (two semitones).From C to D, there's a whole tone (two semitones).For example, a major scale that always follows the formula of whole, whole, half, whole, whole, whole, half: Or we could also see this on any music scale. From F (white key) to G (white key), there're two semitones.From E (white key) to F (white key), there's a semitone.From C (white key) to C♯ (black key), there's a semitone.For example, two consecutive frets on a guitar or keys on a piano or keyboard: It represents the distance between two consecutive notes. Cents between frequencies = 31.767 centĪ semitone, also known as a half step or a half tone, is the smallest musical interval used in Western music.Semitones between frequencies (n) = 0.31767 st.For this particular example, these correspond to: Finally, the semitone calculator will give you the results for the Semitones between frequencies (n) and Cents between frequencies.This frequency corresponds exactly to A4. Similarly, the calculator will indicate the closest musical note to this value.Next, proceed to enter the 440 Hz on the Frequency 2 (ƒ₂) row.For our example, this frequency corresponds to A4 with a deviation of -31.767 cents. After you input this value, a new row will appear, indicating the closest musical note to this frequency you entered and by how much it's on pitch or not.Input 432 Hz on the Frequency 1 (ƒ₁) field.In the rows below, the calculator will show you the distance in number of semitones and cents between the inputted frequenciesįor example, if you'd like to know how many cents are from 432 Hz to 440 Hz:.On the second field, Frequency 2 (ƒ₂), enter the number corresponding to the other frequency.On the first field, Frequency 1 (ƒ₁), input the value of one of your frequencies in hertz (Hz).
With the semitone calculator, you can get the distance between two frequencies in terms of semitones or cents.
