4. Time Signature Setting

ming zhong -

After tapping the Time Signature Button showed in the Chapter 3[3], Pro Metronome will show the Time Signature Setting interface for setting notes and beats.

[1] Time Signature:Press the “+” and “-” on the left side of the screen to adjust beats, press “+” and “-” on the right side of the screen to adjust notes. The range of beats are 1-16, while notes can be set as 1, 1/2, 1/4, 1/8, 1/16, 1/32. Take the image above for example, 4/4 means the note value is 4(quarter, lower numeral) and each bar has 4(upper numeral) beats. Read more about Time Signature and musical symbols on Wikipedia. 

[2] Accent:On one hand, Pro Metronome supports change accent of beat by tapping the corresponding beat block on the screen (refers to the Chapter2[6]). On the other hand, it also supports to set accent in the Time Signature Setting Interface.

Pro Metronome supports 4 modes of accent: f (forte, meaning “loud”), mf(mezzo-forte, meaning “moderately loud”), p (piano, meaning “soft”) and mute. You can change the accent of beats between these modes, which generates different sounds for each beat.

As the below image, green beats represents forte, while blue beats with not arrow (>) represents piano, the gray one represents muted beats.

[3] Subdivision:The default Time Signature Setting interface enables the Subdivision mode. Subdivision divides each beat into different sub-divisions. Pro Metronome allows you to set subdivisions including Swing, Triplet, Dot note, etc. Tap and enlighten your desired subdivision, scroll down for more subdivision patterns.

[4] Polyrhythm: On the right bottom shows a switch. Switch on the button to enable Polyrhythm Mode while switch off it to enable Subdivision Mode.

Polyrhythm is the simultaneous use of two or more conflicting rhythms, that are not readily perceived as deriving from one another, or as simple manifestations of the same meter. The rhythmic conflict may be the basis of an entire piece of music (cross-rhythm), or a momentary disruption.

Polyrhythm is quite useful in Jazz and some modern music styles. For drummers, a simple example is 4 evenly-spaced notes against 3 (4:3). (Refer to Wikipedia for more about polyrhythm)

The Polyrhythm Mode interface is quite similar with the Subdivision Mode. From top to bottom are T.S., Accent, Polyrhythm Settings and other settings, correspondingly.

[5] You can simply tap “+” and “-” button to set the polyrhythm parameters. Some common settings are like 4:3 or 3:2.

[6] Besides, on Polyrhythm Mode, you can switch between Beat Based and Bar Based Mode.

Take 4/4 and 4:3 for example. If current setting is Bar Based, one rhythm divides a bar into 4 beats while the other rhythm divides the same bar into 3 beats. If the current setting is Beat Based, one rhythm divides a beat into 4 sub-beats while the other rhythm divides the same beat into 3 sub-beats.

[7] The display shows the visualized description of polyrhythm. For example, if the label on the left side of “=” shows “Bar”, the polyrhythm mode is Bar Based. However, the label showing note means that the current mode is Beat Based.
