Just copy the result from the table into your DAW.




Enter a tempo in Expert view

Tune to the closest key be clicking the cent-button.

Overview

ToneCalculator helps you bring your songs in tune. Finding the right tempo that fits best to your song.

When something swings below 20 Hertz we can’t hear the frequency but perceive it as rhythm. So the tempo is a frequency below our hearing range, but still a frequency that is either in tune or not.

A big part of music feeling natural is having every part of the arrangement and environment being in sync with the other elements surrounding it. So ToneCalculator also provides you with the correct (in sync) data for your Delays, LFOs, pre delay times of your reverb, attack and release times of compressors and other envelops.

Abbreviations

aug augmented The augmented note is played one semi note higher than usual. In most chases it means the 5th is augmented.
In some chases it is also used for the 4th and the 6th.
dim, -- diminished The diminished note is played one semi note deeper than usual. In most chases it means the 5th is diminshed.
In some chases it is also used for the 4th and the 6th.
maj, + major Major usually refers to the 3rd. The major third is 4 semi tones higher than the root note. A major chord contains a major 3rd!
In a scale there is also a major 2nd and a major 7th.
min, m, - minor Minor usually refers to the 3rd. The minor third is 3 semi tones higher than the root note. A minor chord contains a minor 3rd!
In a scale there is also a minor 2nd and a minor 7th. The minor 7th is also called dominant 7th.
NI Natural Interval In nature the overtones occure in fractions of whole numbers. The standard western tuning (Equal Temperament) distributes the 12 semi tones of an octave equally over the octave (100 cent per semi tone). This results in a slight deviation from the natural intervals (see Fig. 7)
oct8 octave 12 semi tones above the root note, 8th note of a scale. Also double the frequency of the root note.
root1 root note Starting note of a scale. First note of a scale.


Simple View

When ToneCalculator is started it shows up in Simple view (see Fig. 2-1). Here you can enter the key of your song. Than enter the mode, which can be major or minor.
If you are interested in a more sophisticated mode, you can pick a scale from the Scale-menue. If you don't find the scale that you are interested in, go to Details-view and select the Custom scale. Edit the scale and return to Simple-view.
ToneCalculator provides you with all the tempi that are in your selected key and scale in the tempo table.

Metronome

Hit the button with the metronome (Press M) to start it. (see Fig. 2-2)



Use the „turtle-rabbit”-mode for practicing.

Details View

You can start by entering a tempo or a frequency in the first box called Tempo (see Fig. 3-1). The tempo is measured in bpm (beats per minute). The frequency below the tempo is the 8th octave of the tempo, meaning the tempo was doubled eight times and converted in hz (Hertz) which is equal to bps (beats per second).

Note: 60 bpm = 1 bps = 1 Hz (Hertz).

Once you entered a tempo you‘ll find the closest root note to the tempo in the „Root note”-box.
Below the tempo and its frequency is the „cent”-button. Tune the tempo to the root note by pressing the button and setting cent to 0. The indicator in the Tempo-box will turn to green, meaning the tempo is now in tune with the root note.

Tip: If you hold the alt-key and press the „cent”-button the concert pitch will be changed instead of the tempo. Use this function if you want to have an exact tempo, but keep in mind that you have to change the concert pitch in your DAW which is usually set to 440 Hz.

You can also click on the root note and ToneCalculator will provide you with the tempo, that is an octave of the picked root note. Use the OCT+ and OCT- buttons to jump to other octaves.

Duration-tab

Click on Duration to see the times of quarter notes, 8th notes, 16th notes and so on. The 2nd column shows dotted notes and the 3rd column shows triplets. These times can be used for delays, reverbs (pre delay time), compressors and gates. Especially compressors are often not linked to the DAW’s tempo.

To find a good entry point for the pre delay time of your reverb enter your tempo and than use the 64th note (see Fig. 4) as your pre delay time.

Tip: By adding half of a millisecond or rounding the given value up to the next full number, the result may even sound a little bit more pleasing.

Click on Time to toggle between half, quarter and 8th notes. For example if the time of your song is 6/8 choose 8th.

Switch from ms to hz to display the low frequencies. These are used for LFOs (low frequency oscillators) inside your favorite synthesizer.
Switch to Samples to show the duration of the notes in samples. Don't forget to adjust the SampleRate on the right to the SampleRate of your project.

Scale-tab

Click on Scale to activate the scale matrix. Only the selected notes are displayed in the table on the right. You can choose between several presents by clicking on the selector underneath the table or the root note. You can also pick a different scale next to the play-button of the arpeggiator (see Fig. 5)

Figure 5: Scale-tab


Distance-tab

The values shown in this tab give you the distances it takes for the sound to travel in musical times or certain note lengthes. The default value for the speed of sound is in air at room temperature (343.2 m/s).

Positioning your microphone in the given distance will result in a delay that is synced to the tempo of your song.

There are some room simulations with a variable room size. This is where distance-values also come in handy.

Figure 6: Distance-tab


Natural Intervals

This is a table of frequencies as they occure in nature and therefore in the overtones of instruments. In the column „Cent” the difference to the note in equal temperament is shown.

Note: In equal temperament the octave is devided in 1200 cent. So the difference between two neighbouring semi tones is 100 cent.

Important: You can only access the Natural Intervals, when you are in Details view.

Keyboard window

Open this window to practice any scale on the keyboard (Cmd 3). You can customize the scale, play it upwards, downwards or in alternating directions. (see Fig. 8)
The arpeggiator is linked to the pattern selected in the metronome. If you want to practice repetitions of the same note activate One/Beat and change the pattern of the metronome.


Figure 8-1: Keyboard window


Fretboard window

Open this window to practice any scale on the fretboard (Cmd 2). You can customize the scale, play it upwards, downwards or in alternating directions. (see Fig. 8-2)

The arpeggiator is linked to the pattern selected in the metronome. If you want to practice repetitions of the same note activate One/Beat.
To select a different instrument or tuning go to Menu / Tuning (see Fig. 10)


Figure 8-2: Fretboard window


Chords view

Press the Chord button in the fretboard or the keyboard window to see the chords that are contained in the picked scale (see Fig. 8-3).

The root note of the chord will be red, the 3rd (minor or major) will be colored blue, the 5th (augmented, pure or augmented) is colored pink and the 7th (minor or major) is colored yellow.
Move the mouse over a note in the scale to analyse the chord on the fretboard or keyboard.

Again, the arpeggiator is linked to the pattern selected in the metronome. If you want to practice repetitions of the same chord activate One/Beat.

To select a different instrument or tuning go to Menu / Tuning (see Fig. 10)


Figure 8-3: Chord view


Scale

In the Scale-Menu you can find a collection of different scales. Selecting a scale will affect the Simple and the Details view and will change the output of the view's table.
You can select the scale also in Details view under the table or the root note.


Tunings

Select a tuning to open it in the fretboard window (see Fig. 8-2).

Preset

Here you can find a collection of frequencies, that can be an inspiration for your compositions. But be aware of a change in the concert pitch in order to get a specific frequency.

The Default preset will restore the factory setting.
