Music Assistant

Music Assistant is compatible with Leopard, Snow Leopard, Lion, Mountain Lion, Mavericks, and Yosemite.

Brief Description:

Music Assistant was developed to help set a tempo and tune your instruments.

Mac Version 2.3.0 is compatible with Yosemite's default security.


On the left you see the Metronome portion; on the right you see the Tune-up portion. When you launch Music Assistant, the Metronome mode is active by default.

The tempo above is set for 146 beats per minute which is in the middle of the Allegro tempo. You can adjust the tempo up or down using the arrows or jump immediately to the center of a range by clicking on one of the tempo ranges. Click on the "Start" button to start the beat and click on the "Stop" button to stop the beat. As you change the beat using the buttons and the arrows, the tempo display will follow throughout the range of 40 to 210 beats per minute.

If you prefer to see flashes instead of hearing clicks, click on the "Flash" checkbox.


Above, the user has clicked on the "Tune-up Mode" button and has chosen to hear a 440 Hz tone. This is the A just above middle C on a piano. As per the notation, middle C on a piano is C4. On a piano the frequencies go up to the right and down to the left. In this application, a sharp is marked as # and a flat is marked as b. B flat, one full note below middle C is A#3 or Bb3. The user has chosen to hear a sine wave; there are three other choices (square, triangle and sawtooth). When the "Play Note" button is clicked, the A4 tone is heard for three seconds.


The default pitch for A4 is 440 Hz. A drop-down menu also lets you set A4 to 398 Hz or 415 Hz for musicians who play ancient music and 442 Hz or 445 Hz for musicians using pitches other than the 440 Hz North American standard. If you do not like these choices, you can edit the frequency to be between 398 Hz and 445 Hz.

A4 is set for 440 Hz in the other two sub-modes and methods.


Above you see Tune-up in the Select Note mode. All 88 notes on the piano are in the table with their frequencies. The user has scrolled down about half way and clicked on the C4 row. The row clicked is displayed to the right of the "Select Note" button. Again, a sine wave is selected. When the "Play Note" button is clicked, the selected note is heard for three seconds.


Above you see Tune-up in the Select Instrument mode. The user has clicked on the Fiddle row; Fiddle is displayed to the right of the "Select Instrument" button. Immediately to the right of Fiddle is "D4" indicating that the user has played the first two notes and is ready to play the third note (the table shows that the Fiddle tune-up notes are G3, D4, A4, and E5). Clicking on the "Play Note" button replays the D4 note for three seconds; clicking on the "Next Note" plays the "A4" note for three seconds. A sine wave sound is chosen. After the last note (E5 in this case) has been played, the "Next Note" button disappears. This mode allows a user to select an instrument and hear each note for as many times as is needed to tune his chosen instrument. FYI: If there is an asterisk following the note, the note is too low (< 100 Hz) to hear well with small speakers using a sine wave.


Music Assistant has information for 28 instrument tune-ups. Because there are many other tune-up variations, the application includes an Instrument Data window, accessed from the menu bar, where the user can add, delete and change tune-up data. Above you see the Instrument Data window. The user has scrolled down and clicked on the Guitar row. The "Load Fields" button has been clicked and data for that Guitar row has been loaded into the fields below. The button to the left of Note 1 is selected. The next step would be to choose a note from the "Choose Note" drop-down menu and click on the "Use Note" button to update Note 1 data. Data for other notes can be changed in the same manner. When all data is updated as desired, click on the "Update Row" button to replace the row data with the data in the fields. A new row can be added; at minimum, a new row must have a name and Note 1 data. When a row is added to the table, the table is sorted based on the instrument name field. A row can be deleted by selecting a row and clicking on the "Delete Row" button. Click on the "Clear Table" button to delete all rows; click on the "Use Default Data" button to restore the 28 default rows. To hear one second of a note selected in the "Choose Note" drop-down menu, click on the "Hear Note" button. FYI: If you want to delete the last note from the instrument data, use the blank top row in the "Choose Note" drop-down menu.


Above you see the LucyTune Window which can be accessed from the menu bar. Six drop-down menus are provided, each with 21 LucyTuning tones. Set the desired tones and click on the buttons to hear the tones. Settings are saved between sessions. A button linking to the LucyTone web site is provided for the user to investigate this interesting way to tune instruments.


Above you see the Offset by Cents Window which can be accessed from the menu bar. Using controls on this window you can tune notes which are offset from named notes. In this system there are 100 cents between adjacent named notes and you can offset plus (to sharpen) or minus (to flatten) from named notes up to 100 cents, at which point you reach the next adjacent named note. You can select the named note, the offset, see the pulled note frequency and click on the "Play Note" button to hear the note. You can select to play the note for two to six seconds. In the screenshot above, the user has set controls to hear a three second note (445.11 Hz) which is 20 cents below A4 (440.00 Hz). Settings are saved between sessions.
