Small-Time and Large-Time Methods
The previous version featured the small-time usuls of Turkish music. In this version, the large usuls have also been added. This provides access to and the ability to study 54 usuls, ranging from 2-time to 124-time. Additionally, the rhythms are displayed according to the levels at which they are used, the smaller-time-unit rhythm segments from which they are composed, or as a whole. Some rhythm levels are referred to by different rhythm names. These names are also displayed for the relevant rhythms. Consequently, the system contains more than just the 54 basic rhythms. The SymbTr archive, which contains 2,200 works created as part of a project, is accessible via Mus2. As long as these works—as well as those composed by the user—are stored in the archive folder, they could be easily accessed. Now, as you navigate the rhythm list on the left, you can also access works composed using that rhythm directly from this screen. In the demo version, access to a limited number of rhythm entries will be available.
When you click the “Usul” button at the top of the Mus2 window, the following screen opens.

Using the Usul list

The headings in the list function as buttons. When the screen first opens, the list is displayed in order by row number. You can sort the list by row number, procedure name, time, or rank. Clicking the relevant heading again will reverse the sort order. The “Level” column shows the most commonly used order for the relevant method.

When an expression is entered into the search box, the procedures in which that expression appears are listed. For ease of use, there is no requirement to use uppercase or lowercase letters, to type the entire word, or to include punctuation marks.

In this example, a search was performed using the term “cur.” However, although the word does not appear in the title “Aksak Semâî,” it is included in the list. When searching, the system looks not only for items in the list but also for names that appear in the ranks. Since the 16th rank of Aksak Semâî is named “Curcuna,” it appears in the list. If a different name appears under the “usul” heading, that is the usul name given for that mertebe. Therefore, although 54 usuls are mentioned above, the actual number is higher.
Functions of the Buttons
If you hover the mouse over the buttons for a moment, a brief description of their function appears. This information on the buttons indicates the current state of the procedure window.
These are the play and pause buttons.
It ensures the normal arrangement. When clicked, the color will turn green and the chaotic arrangement will be displayed.
When the procedure screen first opens, it will beep twice, taking into account the turn signal at the end of the lane. To keep it beeping continuously, you must click the button.
Rest symbols are used to prevent note shifts when writing music. This button allows you to hide or show rest symbols.
As a general feature of Mus2, notes and rests appear in red when written with the “2nd voice.” Notes and rests played by the left hand are shown in red and written on the bottom staff. You can toggle between colored and uncolored display using this button. For the notes to appear in color, the “Working Sound” option must first be set to “Color” in the “View” tab of the “Settings” screen under “Edit” (> ).

The accompaniment can be provided by a bendir or a kudüm.
With the exception of the two-beat Nîm Sofyan and the three-beat Semâî, all other usuls are composed of combinations of usuls with fewer beats. These buttons ensure that the usul appears either as a combination of the sub-usuls that make it up or as a single, unbroken whole.
Each style has a default tempo setting. During practice, you can change the tempo using this button. You can adjust the tempo in small increments using the left and right arrow keys, or by dragging the blue bar to make larger changes.
Some methods can be used with different degrees (denominators). In this example, the method in question is used with three different degrees, and the number 4 in green indicates the degree most frequently used in works created with this method.
This feature allows the selected time signature to be exported to the Mus2 score page either in parts or as a whole, depending on its current state on the screen. The example below shows the Türk Aksağı (5/8) time signature exported using two different options.

Use of Usul with the Archive

When a style is selected, works written in that style are filtered from the archive folder and displayed in a list. You can sort this list by clicking on the column headers. Additionally, double-clicking a work entry in the list opens the work in Mus2. If an archive folder has been created previously and the “Makam” and “Usuller” columns are empty, clicking the “Update Archive Database” button on the screen opened via the “File” > “Open Archive” menu will refresh the data.
