Appcompanist Help


Song Position Slider

Skip anywhere in the piece by sliding the position indicator on the line. The time indicator displays your position in minutes and seconds.

Song Information

Title, Greater Work, and Composer are listed for every song in the Library List.

Forward/Back Arrows

Forward and back arrows to the right and left of the Play/Pause button let you skip to the start of the current title, or skip forward or backward to other titles in the search result list or playlist you are in.


Click on the key signature and use the wheel to transpose up to 11 half steps in either direction from the originally recorded key. The piece will remain in the new key until you change it again.

Melody Blend

To hear the melody played along with accompaniment at higher volume, touch the “melody” button to the right of the key signature. Use the slider that appears when “melody” is selected to adjust the blend from roughly 60/40 melody/accompaniment at the far left to melody only at the far right. You can also tap “Blend” or “Melody” to immediately set the slider to one of the two extremes. Tap -8va, 0va, or +8va to hear the melody in one of three octaves. To turn off melody and return the accompaniment to full volume, simply click the melody button again. (Note that in many vocal pieces, the melody is doubled in the accompaniment, as specified by the composer, arranger or publisher. So you may hear melody even when the melody button is not selected.)

Tempo Slider

Place your thumb or finger on the tempo slider and move left or right to control tempo while the piece is playing or to set a tempo before play. Max tempo to the right is 200% of the recorded tempo, while the minimum to the left is 50%. An indicator to the upper right of the slide displays your relative tempo. The tempo will stay wherever it is when you remove your thumb or finger from the slider. To quickly return to “a tempo,” swipe up with your finger or thumb anywhere on the screen OR hit the “a tempo” button below the slider. You may also set a new “a tempo” position by moving the slider to your desired tempo, removing your thumb or finger, and touching the percentage marking to the upper right of the slider. You will see the words “a tempo” move directly underneath the button on the tempo slider wherever it is. Now you can move tempo with the slider again and quickly return to your new “a tempo” by either swiping up or clicking again on the “a tempo” button. At any time, you can return to the originally recorded tempo (100%) by clicking on the word “Tempo” to the upper left of the slider. The tempo slider displays in gold to let you know when you are on the button and in control of the tempo.

Fermata Button (Patent Pending)

Press and hold the fermata button any time during play in order to facilitate musical pauses, cadenzas, recitatives, or other times in which a musical fermata would be indicated for the accompanist. The piece will not progress while you are holding the button down. If pressed during a chord or note, that chord or note will ring until the fermata button is released or until it naturally decays as it would with a live accompanist. The next musical chord or note in the accompaniment will play immediately when the fermata button is released, no matter how long it is held.

The Fermata button also provides you additional control and accuracy for those songs in which you are meant to begin singing prior to or simultaneously with the accompaniment, or when you have stopped singing and want to be able to accurately enter at a specific spot with the accompaniment. Any time the piece is stopped, including the beginning, you can press and hold the Fermata Button rather than the “Play/Pause” button. You can now take your breath or sing your pickup notes and bring the very next note or chord of the accompaniment in, in tempo, the moment you release the button.

Pitch Check

While stopped, before pressing Fermata, you can also double check the pitch of your next melody note as many times as needed by clicking the “eighth note icon” to the right of the “Fermata” button.


Like any music play interface or device you can play or pause the piece at any time using the Play/Pause button. The double left arrow to the left of the Play/Pause button will return you to the beginning of the selected title. When it is clicked twice it will open the next title back in playlist or search-selected list that you are in. When held down, it will scan back quickly through the recording and begin playing again when released. Similarly, the double forward arrow will move you forward to the next piece in your playlist or search-selected list if clicked once, and will scan forward in the recording when held.


The small icon with three dots at the bottom right of the player screen allows you to share the currently selected title with another Appcompanist subscriber; add the title to any current playlist or create a new playlist starting with the current title; and reset any automatically saved song settings to the originally recorded settings.  Touch either of the first two options and follow the on-screen prompts to complete the actions.

Static song settings (as of Version 1.1) such as key, tempo, melody blend and melody octave are all automatically saved when you close a song, so that the next time you open that song, it will play exactly as it did when you left off.  Tap “Reset Song Settings” to clear all settings and restore to the original recorded version.


Audio Output

The icon to the left of the Play/Pause buttons allows you to choose between the phone’s internal audio (speaker or headphones), and any Bluetooth speaker you have already set up in your phone. Use this button at any time to move back and forth between audio outputs without leaving the app. (To set up a new Bluetooth speaker – go to settings/Bluetooth on your phone. Once the devices connect, they should always appear in the Audio Output option of Appcompanist when it is on and in proximity)

Navigation Bar

A navigation bar is always visible at the bottom of Appcompanist, allowing you to easily move between the Player, Playlists, Search Screen and Info/Help.


Press the Search icon in the Navigation Bar at the bottom of your screen at any time to view the Appcompanist Library List. Type a title, greater work or composer in the search box at the top of the page to find a specific piece. You may also type other complete keywords that pertain to the database organization of the library such as “baritone” “opera” “Italian” etc. To quickly narrow the library list you can also use Filters. Click the “Filters” button and choose the types of pieces you would like to see displayed in the Library List. You can set multiple filters in the categories of Genre, Voice Type, and Language. The “Filters” button will appear red whenever filters are in use. You can deselect any filter at any time or “Clear All” filters and return to the Search List by clicking “Done” after you make your selections.

A button at the top center of the Library List also lets you sort the list at any time by Genre, Language, Voice Type, Composer, Greater Work (Opera, Song Cycle, Show, etc.), Title, or New.  Headers will appear in the Library List according to the Sort criteria you’ve chosen. Only the Title and New sorts don’t contain headers as they display all titles in alphabetical order.  If you select “New” a list of all titles in the library will appear, starting with an alphabetical listing of titles added within the last 30 days, followed by an alphabetical list of titles in the library for more than 30 days.  In Genre, Language, Voice Type, Composer, and Greater Work, you can open and close headers to view the lists of titles in a more organized fashion. To see the list of titles beneath any header, tap the triangle to the right of the header name. You can also tap the triangle to the right of any title in the Library List to view more complete information on that title including composer, greater work, voice type and language. Using a combination of Filters and Sort, you can organize the display the library in almost any configuration best suits you.

The “Playlist+” button to the top right of the Library List will allow you to add one or more pieces from your Library List to your desired playlists. Click the “Playlist+” button, select the songs you want to add to a playlist by checking the open circles to the left of any title, and hit “Add to Playlist” at the top right of the Library List. Follow the onscreen prompts to either add them to an existing playlist or create a new playlist to which you can add the selected titles.


Press Playlist in the Navigation Bar at the bottom of the screen at any time to view your Playlists. Click on the name of any playlist to view the song titles within that playlist. From within any playlist you can select a title to open it in the Play Window, and to use the Forward and Back arrows in the Player to quickly navigate through the songs in that list. Press the “Edit” button on the top right of any Playlist to move and rearrange titles within the playlist using the list lines icon to the right of each title, or delete titles from that playlist using the red delete buttons to the left of each title.


Press the Info/Help icon in the Navigation Bar at the bottom of your screen any time to view your subscription type, share the app with a friend, or link directly to the website in order to view tutorials, watch videos, ask questions, report a problem, view upcoming recordings, suggest new titles, and explore future app features.
