An essential feature of BARBARA the Metronome is that it can handle music in which the time signature of a bar is not always the same as in the previous bar. The term 'mixed meters' is used to describe such music.

BARBARA works on iPhone, iPad, and iPod touch.

Please, scroll down to see examples of how BARBARA can be used. BARBARA is a flexible tool for both professional and less professional musicians.

The following are links to 2- to 3-minute videos that show some great features of BARBARA.

You can use the App Store App in your iPhone, iPad, or iPod touch to get BARBARA. If necessary, please, seach with words "BARBARA the Metronome". BARBARA will work in devices that can use version 13.1 of the iOS operating system. This means that you need to have iPhone 6s or some newer device for BARBARA. An Android version of BARBARA is under development.

Programmable with Buttons

BARBARA provides many buttons with which to choose bars for playing. The activity of choosing bars for playing is called programming. The word 'programming' may frighten some people, but programming BARBARA means just pressings on buttons that are marked with familiar musical symbols.

Rests and Repeats

In addition to the buttons for bars, BARBARA has buttons with rest and repeat symbols. It is thus possible to create sequences of bars that contain silence as well as sequences that are played a certain number of times.

A Traditional Metronome

Although BARBARA is designed to help with 'mixed meters', it is easy to use it as a 'traditional' metronome. For example, when a single 4/4 bar is defined and the Loop button is pressed, BARBARA will play the 4/4 rhythm.

There is the special feature that if you do a long press on the Play button, BARBARA starts producing a traditional monotonous metronome sound.

Increasing Tempo

Here BARBARA is playing twelve 4/4 bars so that those bars are played 6 times, and after each playing the tempo is increased by 20. The numbers above the bar symbols indicate what has been programmed. The numbers below the bar symbols are updated while BARBARA is operating.

The above sequence of bars is explained in more detail in the following picture.

Here you see how BARBARA can be made to repeat a certain sequence of bars, and how tempo can be increased for each repetition. It is supposed here that a musician would like to practice twelve 4/4 bars of music in increasing tempo. In place of those twelve bars you could put a list of other bars.

By using full rests and alternative metronome sound, it is possible for the musician to prepare himself/herself before the twelve bars need to be played. BARBARA can use two kinds of metronome sounds. The buttons with dark numbers produce the alternative sounds.

Every 4th Bar Silent

Sometimes it may be useful that a metronome is silent between some bars.

If the Loop button is pressed when the above simple sequence is programmed into BARBARA, the metronome will play the 4/4 rhythm so that every 4th bar is silent.

BARBARA will automatically store all sequences of bars that are programmed, and you can also name the sequences. All sequences can be found, and used later, by pressing the Lists button.

Programming Minutes

Let's suppose that a musician would like to play 10 minutes the 4/4 rhythm in 120 beats per minute, and immediately after that he or she would like play 10 minutes the 3/4 rhythm in 140 beats per minute.

The above sequence could give the timing for this hypothetical practice. If tempo is defined in a sequence, BARBARA can be programmed using minutes. In the above case BARBARA has calculated that 300 4/4 bars are needed for 10 minutes when the tempo is 120, and 467 3/4 bars are needed to play 10 minutes when tempo is 140.

Two full rests are used to mark the change of tempo and time signature.

A Cello Player's Opinion


Janne Varis, a cello player in Oulu Symphony Orchestra, says: "I have used BARBARA for three years. This metronome is an important tool which saves my time when I need to practice pieces that contain varying time signatures."

A Pianist's Opinion


Eeva Havulehto is a professional pianist and piano teacher who has studied in the Sibelius Academy in Helsinki. She says: "I just love BARBARA. Finally I can easily clarify for myself the changing time signatures that are common in the pieces that modern composers make."

Instructions

BARBARA has been described as an easy-to-use app. Once you understand the logic how it works, you may not need any instructions.

If you are going to program complicated sequences of bars, it may be useful to read the detailed using instructions, which can be found through this link.

You can find the instructions also by pressing the Info button of BARBARA.
