The Altered Scale scale contains 7 notes: G, Ab, Bb, B, Db, Eb, F. With a formula of 1 - b2 - b3 - 3 - b5 - #5 - b7, it uses all seven notes of the diatonic system. This advanced scale opens up sophisticated harmonic possibilities.
The G Altered Scale scale is constructed using the interval formula 1 - b2 - b3 - 3 - b5 - #5 - b7, which means it contains the intervals Root (1), Minor Second (b2), Minor Third (b3), Major Third (3), Tritone (b5/#4), Minor Sixth (b6), Minor Seventh (b7) above the root G. The notes are G, Ab, Bb, B, Db, Eb, F. Starting from the G major scale (G, G#, A, A#, B, C, C#, D, D#, E, F, F#), each interval contributes to its distinctive dominant character. Key characteristics: 7th mode of melodic minor. Every interval altered.
G Altered Scale sounds tense, bluesy, and directional. The combination of a major third and minor seventh creates the classic dominant tension that wants to resolve.

10 minutes: Practice the scale with a metronome at 60 BPM. Play one note per beat ascending, then descending. Gradually increase to two notes per beat (eighth notes) and four notes per beat (sixteenth notes). Focus on timing precision.
20 minutes: Apply the scale over a backing track in G major. Improvise melodies using only the Altered Scale scale notes. Experiment with different rhythmic patterns, slides, bends, and vibrato. Focus on musical phrasing.

Common Mistakes to Avoid:
- Playing too fast before understanding the scale's sound character
- Not listening to the intervals individually
- Ignoring the scale's unique character (each scale has a distinctive mood)
- Skipping the descending practice — descending is equally important
Advanced Tips: Explore the scale's modes and related scales. Practice with odd time signatures and asymmetric rhythms. Use the scale over non-standard chord progressions to discover new sounds.
