How to Play B Altered on Mandolin
Begin by locating B on your instrument and play through the 7 notes of the Altered scale slowly, ensuring each note rings clearly before increasing speed.
The B Altered scale contains 1 sharp (D#). This scale does not follow a traditional major or minor key signature, so reading from sheet music may require accidentals.
Practice Routine
Practice the B Altered scale by playing it ascending with one rhythmic feel (straight eighth notes) and descending with another (swing or triplets) at 100 BPM. This dual approach trains both technical accuracy and rhythmic versatility with the 7 notes of the scale.
Exotic scales like the Altered often work best as a melodic layer over a single root drone on B. Let the unique intervals speak for themselves without frequent chord changes. This scale is especially effective in fusion contexts.
Mandolin Tips
Practice the B Altered scale slowly and evenly on your instrument, focusing on tone quality for each of the 7 notes before building speed. Aim for a dissonant quality in your phrasing to match the natural character of this scale.
