Patterns can be played identically in any desired key, changing only the starting position. As a rule, the thumb, numbered 1, is not used. Single-note bass lines are often labeled 'B.S.' (bass solo or bassi soli), especially when they extend above the middle of the staff.ДЄs with the piano, fingers are numbered 2 to 5, starting with the index finger, mirroring right-hand fingering. For example:Д«ass notes to be played on the major third (counterbass) row are often indicated by repurposed ' tenuto' lines below the notes (as in the E bass note in the example above), or underlined note names or numbers. Different accordions contain sets of reeds in different octaves, which may also be activated or muted by the accordion's register switches. The Stradella system does not have buttons for higher and lower octaves.

Within this convention, the written octave for bass and chord notes is arbitrary. The first instance of a chord is labeled M, m, 7, or D (or d, or dim) to a signify major, minor, dominant seventh or diminished seventh, with the label applying to subsequent similar chords, until a different type of chord occurs or a new system (line) of music begins. In staff notation written for Stradella bass, notes below the center of the bass-clef staff are bass notes, and notes above the center of the staff usually indicate chord buttons. In most Russian layouts the diminished seventh chord row is moved by one button (so, for example, the C diminished seventh chord is where the F diminished seventh would be in a standard Stradella layout), so it is more easily reached with the forefinger.ДЄs the buttons are on the front face and cannot be seen by the player, a small depression, hole or bump is made on the central C button in the root row, as well as on other selected root-bass buttons, such as the A в™ and E, which are four buttons away in either direction.

For example, an augmented seventh chord can be created by using the dominant seventh chord button and adding an augmented 5th from the right-hand manual or from one of the bass or counterbass buttons. Modern Stradella systems omit the 5th from these two chords, allowing for more versatility.

Early accordions sounded four pitches for the seventh and diminished chords. In modern accordions, each chord button sounds three individual pitches. Larger accordions offer some control over the voicing with register switches. Each bass note, and each pitch in a chord, is usually sounded simultaneously in multiple octaves.
